THE QUARTERLY JOURNAL OF THE CHEMICAL SOCIETY. XXV.-Decompo~tion of Gaseous Compouoeds by Electrical Incandescence. BY HENRYBUFFAND A. W. HOPMANN. THEexperiments described in the following pages were undertaken in the hope that the slow decomposition of compound gases by the long-continued passage of electric sparks might be effected by the spark-current of the induction-coil with such rapidity and precision as to furnish a simple experimental illustration of rela-tions with dficulty attainable by other methods. The relation of the spaces occupied respectivel? by a compound gas and by the sum of its gaseous constituents is but rarely capable of synthetical demonstration. In most cases this relation can only be exhibited by analytical operations which are not always compatible with the conditions of a lecture experiment The successful application of the spark-current appeared to promise a considerable simplification of these processes.With this view we have studied the action of the current produced by a powerful Ruhmkorff coil on the more frequently occurring compound gases and on the vapours of several liquids of low boiling point. At the same time we examined the deportment of these gases and vapours under the influence of iron or platinum coils electric- VOL. XII. U BUFF AND HOFMA" ON THE ally incandescent together with the effects produced by the high temperature of the electric arc. The mode of performing the experiments may be briefly stated. For the convenient introduction of the spark-current into the gas confined over mercury a fine platinum wire was fused into the shorter limb of R thin U-shaped glass tube and filed offso as scarcely to project beyond the glass.At a distance of a few millimetres from the platinum pole thus obtained the loop of a second platinum wire was thrown over the tube and the wire wound round the tube until it nearly reached the bend as seen in fig. 1. The tube was then fll.e$ with mercury, FIU. 1. and the shorter limb introduced into the graduated gas-tube inverted over mercury in a deep cylinder- ti*augh. The pole-wires of the induction coil being now introduced the one into the open end of the U-tube filled with mercury the other into the mer-cury of the cylinder-trough the spark .current could be established or interrupted at will by either de-pressing the U-tube until the outer platinum wire reached the mercury surface or by lifting it so as to b;e& coiitact.It need scarcely be mentioned that in most cases an orclinzlry eudiometer or a syphon-eudiometer may be used with the same effect. They are not however to be recommended for the decomposition of those gases which yield a deposit of carbon inasmuch as the separation of this element in the form of a filament between the !:latinurn points is apt to interrupt the ex-has been provided by Professor Bunsen with a simple but ingenious little contrivance IVhich renders it particularly adapted for lecture experiments. It consists of a small glass tube com- municating with the eudiometer near the bend the outer end of which is closed by an India-rubber tube provided with a glass valve.By a gentle lateral compression the metal rum out through the opening between the glass and caoutchouc until the mercury msumes a level position in both limbs of the instrument when the true change of volume becomes at once apparent. The decompositions by incandescent coils of iron and platinum or by the electric arc were accomplished by an arrangement DECOMPOSITION OF GASEOUS COMPOUKDS. similar to that previously mentioned. For experiments of this description both limbs of the U-tube remain open; the iron or platinum wire is inserted into the shorter FIG.2. limb and then coiled downwards round the tube.1 Since the powerful heat emitted from the coil is apt to crack the U-tube we have found it convenient to sur-round the latter with a somewhat wider glass tribe mhich separates it from the incandescent coil. (See fig.2.) The U-tube as in the previous case is filled with mer-.cury and the pole wires of the battery are adjusted in a similar manner. By depressing the U-tube until the lower end of the coil dips into the mercury the coil may bk readily heated; by raising this end to a proper height above the level of the mercury in the tube the arc may be conveniently adjusted. Our experiments were made partly in Giessen with the Ruhmkorff coil in the University collection; partly in London with a splendid instrument which Dr. Bence Jones had liberally placed at our dis-posal.AMMONIA. Of all the compound gases ammonia appeared to promise the simplest and most striking result. During the decomposition of this body into nitrogen and hydrogen the original volume of the gas is as is well known doubled. Priesthy* had observed that the passage of electric sparks through ammonia expands its volume giving rise at the same time to the separation of an inflammable gas; and the further development of this observation became in the hands of the elder Berthollet the key to the com-position of ammonia. The spark exerts simply a thermal effect in this decomposition as is obvious from the fact likewise observed by Priestley that the decomposition takes place also when the gas is passed through a red-hot narrow glass tube.More recently some experiments upon the action of electrically incandescent pla- tinum wires upon ammonia were published by Grove,? in an interesting paper to which we shall have frequently to refer. * Kopp Geechichte der Chemie Bd. 111 246. t Phil. Mag. Dec. 1845. u2 BUFF AKD HOFMANN ON THE Grove found that a complete decomposition of ammonia may be accomplished by this process. Our experiments have furnished the following results. Even in favourable weather several hours are required in order to decompose 4 C.C. of ammonia by means of the spark- current produced by a powerful frictional electric machine. The decomposition by electrically incandescent platinum wire is likewise rather slow. 4 C.C.of ammonia in which a platinurn wire of 60-length and 0.2-diameter was heated to whiteness by means of 6 Bunsen elements were by no means completely decomposed even after the lapse of an hour. On the other hand by employing 20 elements and a platinum wire of 0.4-diameter the length of which was regulated by lifting or depressing it in the mercury until the most powerful white heat had been attained we succeeded in perfectly decomposing 6*25 C.C. of ammonia in from 20 to 25 minutes. A very remarkable effect is obtained by means of the electric arc produced by 20 elements. By heating the platinum wire opposite the mercury to incipient fusion 23c.c. of ammonia were so entirely decomposed in 5 minutes that water injected into the ;tube no longer exhibited an alkaline reaction.Rapidly as the decomposition is accomplished in this manner this mode of experimenting nevertheless is scarcely to be recommended inas- muehas the mercury heated to ebullition coats the tubes with an opaque metallic mirror not to speak of the risk of breaking the glass tubes by the intensity of the heat. The decomposition of ammonia may be most rapidly and elegautly accomplished by the spark-current of the induction-coil. From 3 to 4 Bunsen elements are quite sufficient. The spark- current traversing the ammonia exhibits a violet 1ight surrounded with a blue edge. At first the mercury falls rapidly the rate of expansion of course diminishing with the progress of the decom- position; but in 5 minutes the decomposition of a moderate volume of ammonia is accomplished.The original volume is then doubled and the spark-current exhibits the pure violet light cha- racteristic of hydrogen. 5.5 C.C. of ammonia furnished in 4 minutes 11C,C. gas; 11.3 C.C. of ammonia 22.7 C.C. of gas. Water injected into the tube no longer produced a diminution of volume although it sometimes still exhibited a faint alkaline reaction. This also entirely disappeared when the spark-current was con-tinued a few minutes longer. DECOMPOBIrlON OF GASEOUS COMPOUNDS. It appeared of some interest to make a few comparative experiments with some of the basic derivatives of ammonia. METHYLAMINE CH,N.* On passing the spark-current through methylamine gas the tube becomes filled with white fumes which when the current is interrupted are condensed into a network of long white needles.Water injected into the gas exhibits the hydrogen already eliminated and the solution contains cyanide of methyl-ammo- nium. This result is of some interest as it shows that in the first stage the action of the current induces the formation of simpler compounds. On renewing the current the white crystals entirely disappear and are replaced by a black resinous substance which is deposited in considerable quantity within the tube at the same time the volume of the gas is considerably expanded. The decom- position is howeker by no means complete and we found it impossible to obtain the theoretical volume even after a long-pro-tracted passage of the current.5.1 C.C. methylamine gas gave after 20 minutes 13.5 c.c. and after 10 minutes more 13.7 C.C. of gas the continued passage of the current produced no further change. Assuming the decomposition of the methylamine -to be perfect the original volume should have trebled (1 vol. of methy-laminegas affording + vol. of nitrogen and 2+ vol. of hydrogen) and the above experiment should have therefore furnished 3 x 5.1 =15*3 C.C. of gas. TRXMETHYLAMINE C,H9N. The decomposition by the spark-current proceeds but slowly a considerable quantity of a tarry substance separating and the esperiment being frequently interrupted by the formation of a carbon bridge between the platinum points. 3.7 C.C. of tri-methylamine-gas furnished after 50 minutes a maximum volume of 14.4 C.C.of gas. Perfect decomposition into the elements should have yielded 5 times the original volume (4 vol. of nitrogen and 4+ vols. of hydrogen) i.e. 5 x 3*7=18.5 C.C. of gas. * c = 12. BUFF AXD HOFMANN ON THE ETHYLAMINE C,H,N. The decompdion which on account of the fluid condition of this body was accomplished at a temperature of 36' C. exhibited phenomena perfectly similar to those observed in the previous cases. After 30 minutes the gas had reached a maximum expan-sion; 5.2 C.C. ethylamine gas gave 15.1 C.C. of gas which was no longer alkaline and possessed the odour of cyanide of ethyl in a marked manner; at the same time a considerable quantity of tarry matter wits separated. Theorctically the original volume should have quadrupled (3vol.of nitrogen and 39 vol. of hydro-gen) and the above experiment should have yielded 4 x 5.2 =20.8C.C. of gas. CYANOGEN. According to the observations of Sir Humphrg Davy the continued passage of the electric spark decomposes this gas into carbon and nitrogen gas of a volume equal to that of the cyanogen employed. The action of heat upon cyanogen has been studied by Gay-Lussac who states that this gas may be passed through red-hot porcelain tubes containing gold or platinum without undergoing any decomposition. We found that cyanogen may be perfectly decomposed by electrically incandescent iron wires. We employed in the experi- ment a battery of 20 elements of Bunsen; the same power was used in all other similar experiments in which the number of elements is not especially mentioned.50 C.C. of cyanogen gas lea after half-an-hour the same volume of nitrogen which was no longer affected by potassa. But in order to produce this effect it was necessary to introduce not less than six consecutive wires the first two or three being transformed into cast-iron and fusing almost immediately. . The decomposition is more rapidly effected by the electric arc the carbon separating in thick flakes; &om 30 to 40 C.C. of gas being used not a trace of cyanogen was left after 10 or 15 minutes. In some of these experiments we observed an appreciable increase of volume. Thus in decomposing 56 C.C. of cyanogen we obtained 40C.C. of gas. Iu other experiments even a larger expansion was observed.We soon found that this effect was due to the presence of moisture in the gas the ratc of increase DECOMPOSITTON OF GASEOUIJ COMPOUNDS. diminishing in proportion as more and more attention was paid to the perfect desiccation of the gas itself and of the mercury; but since the latter is generally heated nearly to ebugtioa it is diffi-cult to prevent the rising of a last trace of moisture. When the cyanogen gas mas purposely moistened with a drop of water 39.2 C.C. expanded to 56 C.C. in twenty minutes. Potassa being now injected it was seen that a considerable quantity of cyanogen had remained undecomposed. The gas left after treatment with potassa was inflammable and burned with a blueedged ‘flame thus indicating the presence of carbonic oxide.It is obvious that the water acting upon the cyanogen gives rise to the forma- tion of carbonic oxide carbonic acid and ammonia the latter then splitting into nitrogen and hydrogen. The spark-current of the induction coil is very little adapted to the decomposition of cyanogen; the current traverses this gas with a white red-edged light but is soon interrupted by the separation of carbon filaments between the platinum points. 31 C.C. of cyanogen gas mere reduced to 29c.c. after the current had passed for 14 hours. Injection of potassa showed that 21 C.C. of cyanogen had remained undecomposed. The slight diminution of volume was probably due to the absorption of cyanogen by the abundantly separated carbon.NITROUS OXIDE. The alterations which this gas undergoes when submitted to the action of electricity and of heated metals have been studied by Gay-Lussac and Thhard and also by Sir H. Davy. In both cases free oxygen together with higher oxides of nitrogen was observed. We found that an incandescent iron coil readily decomposes the nitrous oxide with formation of sesquioxide of iron a volume of nitrogen equal to that of the gas employed being left behind. From 3 to 4 minutes are sufficient for the decomposition of 30 or 40c.c. of nitrous oxide. A similar effect is produced by the electric arc issuing from an iron point. The incandescent platinum coil does not produce an immediate change but soon red xapours begin to appear and the volume of the gas is considerably expanded.After 5 or 6 minutes a maximum effect is reachcd and now the volume diminishes again BUFF AlSD HOFMANN ON TIIE and the red vapours disappear. In the first stage of the reaction the nitrous oxide seems to split into oxygen and nitrogen; the two gases afterwards partially unite to form hyponitric acid and are fixed by the mercury. The theoretical volume of volume (1 vol. of nitrogen and 3 vol. of oxygen) is therefore never reached ; a result which also follows from Grove's" observations. In an experiment of this kind 44.8 C.C. nitrous oxide furnished after 6 minutes a maximum volume of 59-4 C.C. of gas; assuming the decomposition to be perfect 1+ x 44*8=67*2 C.C. gas should have been obtained. The spark-current slowly decomposes nitrous oxide into nitrogen and oxygen which when the current is continued partially unite to form red vapours.9 c.c. after two hours and a half gave 13 C.C. of gas which exhibited a slightly reddish tint. In case of perfect decomposition 14 x 9= 13+C.C. should have been obtained. On passing the current for an additional one hour and a half the volume was reduced to 8 C.C. ; hyponitric acid having been formed and fixed by the mercury. NITRIC OXIDE. The effects of electricity and of heat upon this gas have been examined respectively,by Priestley and by Gay-Lussac. Inboth cases nitrogen is separated higher oxides of the latter element being formed at the same time. Both Sir H. Davg and Gay- Lussac decomposed nitric oxide by red-hot metals which were oxi- dized a volume of nitrogen equal to half the original volume of gas being left behind.Inour experiments the decomposition of the nitric oxide suc-ceeded particularly well by the incandescent iron coil. The metal burns with splendid scintillations continuing for 3 or 4 minutes according to the volume of the gas; as soon as the scintillation ceases the experiment is finished. Inthe first stage of the reaction red vapoum are perceptible which however rapidly disappear ; as long aa they are visible the iron burns with a greenish light. When the experiment is finished a volume of nitrogen is left behind equal to half the original volume. The decomposition is so complete that the residuary gas becomes neither red on ad-mission of oxygen nor black on injection of sulphate of iron.* LOC. Cit. p. 272. DECOJIPOSTTIOX OF GASEOUS COMPOURDS 281 46-9C.C. nitric oxide submitted for 5 minutes to the action of the red-hot iron coil left 23.2 C.C. of pure nitrogen. Such accurate results however are obtained only when perfectly pure nitric oxide is employed; in most experiments the residuary gas amounts to more than half the original volume the ordinary mode of preparing the gas-copper turnings and nitric acid-yielding almost invariably an admixture of nitrogen gas. Nitric oxide is but slowly decomposed by the spark-current of the induction coil. In the commencement of the experimeut red vapours are generated which gradually disappear the mercury becoming considerably tarnished.l2a C.C. of nitric oxide siib-mitted to the current for 13 hour were reduced to 64 c.c. which the further passage of the current brought down to 6 C.C. of nitro-gen the oxygen together with a small quantity of nitrogen being absorbed by the mercury. Incidentally we have made a few observations on the passage of the spark-current through atmospheric air. The facility with which the celebrated Cavendish* experiment may be performed by this means has been already pointed out by Bequerelt and by IJ0ttger.S After a few minutes the passage of the spark-current generates distinctly visible red vapours in a flask filled with dry atmospheric air; moist blue litmus paper becomes red in a few seconds. The presence of water considerably facilitates the com- bination of nitrogen and oxygen.12.5 C.C. of moist air when submitted to the current for 2 hours were reduced to a minimum volume of 9-25 C.C. of gas which though not entirely freed from oxygen no longer supported combustion. To reduce 12.55 C.C. of dry air to 9.25 C.C. it was necessary to pass the current for not less than 8 hours. CARBONIC OXIDE. The gas when perfectly dry,resists the action of incandescent platinum and iron even when the heat is so powerfully urged as to fuse the latter into large globules. * Pbil. Traaa 1784. + Th.du Moncel'e description of Ruhmkorff'e coil. $ Kopp and Will's Jahresbe-richt 1858 p. 102. BUFF AND HOFMANN ON THE The el&ric arc when issuing from iron is likewise without effect.Carbonic oxide confined over water when submitted to an incandescent platinum coil is transformed into carbonic acid as was already observed by Grove,* the converted carbonic oxide being replaced by an equal volume of hydrogen so that the injection of potassa restores the original volume. The spark-current passes through dry carbonic oxide with a blue light; it is without effect CARBONIC ACID. It is well known that in the presence of red-hot iron car- bonic acid is reduced to carbonic oxide. This reduction how- ever is extremely slow and difficult. In order to transform 30 C.C. of carbonic acid into carbonic oxide the action of the most power-ful electric arc is required for three-quarters of an hour. The volume of the residuary carbonic oxide is equal to that of the carbonic acid employed; injection of potassa no longer affects the volume of the gas.In several experiments in whicli the actioii was not continued longer than a quarter of an hour not more than about one-half of the carbonic acid was found to be cm-verted into carbonic oxide the original volume remaining likewise unchanged. In some cases however a very appreciable increase of volunie was observed the cause of which was soon found to be the accidental use of steel springs the carbon of steel affording an additional supply of carbonic oxide. With soft iron this increase of volume never occurred. The imperfect decomposition of carbonic acid by the spark into carbonic oxide and oxygen was observed many years ago by Henry and by Dalton.It may be readily exhibited by the spark-current of the induction-coil. The spark traverses thc gas with a violet light. In the commencement of the experiment the expansion is very appreciable; 73 C.C. of carbonic acid after a few minutes became 83 C.C. ; but the further decomposition proceeded with extreme slowness until after the lapse of half an hour the accumulated carbonic oxide exploded with the liberated oxygen when the original volume of the carbonic acid was restored again to undergo a similar set of changes. Unfortunately the decomposition of carbonic acid by the spark-current is not suffi-lli Lac. cit. p. 272. DECO\IPOSITION OF GASEOGS COMPOUNDS. cientlg rapid to admit of being exhibited as an instructive lecture- experiment.BISULPHIDE OF CARBON. From 30 to 40 C.C. of bisulphide of carbon vapour at a tempe- rature exceeding 60° or 70°,were perfectly decomposed in a few minutes by an incaudescent coil of iron the iron being converted into sulphide and the carbon liberated. The platinum coil like- wise produced the decomposition bixt much more slowly. In the latter case the carbon floating on the surface of the mercury contained a considerable proportion of free sulphur. The sulphide of carbon corresponding to carbonic oxide the for-mation of which from the deportment of carbonic acid under similar circumstances might have been expected was not produced in our experiments. When the tubes had become cold no gaseous product remained.MARSHGas. According to Da1t on the passage of electric sparks transforms marsh gas into the double volume of pure hydrogen the carbon being separated; and from Sir H. Davy’s experiments it appears that electrically incandescent platinum wire produces the same effect. By passing the spark for 30 hours however through n small volume Bis c h off succeeded in decomposing only about + of the gas empyreumatic products being invariably produced at the same time. The decomposition was not more perfect when the gas mas passed through red-hot porcelain tubes and very recently Magnus* has shown that the most intense white heat is required to split marsh-gas into its elementary constituents. The marsh-gas used in our experimeuts had been preparcd by carefully heating acetate of sodium with lime and hydrate of potassa.In none of our experiments did we succeed in perfectly decomposing this gas. The incandescent iron coil acts but slowly. In half an hour 16 C.C. were expanded to 26 c.c.; the iron wire remained bright but by absorption of carbon it had become very brittle The experiment afforded a good opportunity for observing how difficult it is to maintain the incandescence of the wire when the hydrogen begins to preponderate in the tube. * Pogg Ann XC,1 BUFF AND LIOB’MAXN ON THE A somewhat better effect is obtained by allowing the electric arc issuing from iron to pass through the gas. 29 C.C. of marsh gas thus became 53 C.C. in a quarter of an hour. The most perfect result is furnished by the spark-current of the induction coil.The spark traverses the gas with a pale blue light rapidly changing to violet. 10 C.C. of gas in half an hour became 18.3c.c. which did not increase on the further passage of the current. No carbon was separated on the sides of the tube but between the platinum points a thin carbon filament was deposited which had to be removed once during the experiment. The resi- duary hydrogen had a peculiar odour and burned with a slightly luminous flame. OLEFIANT GAS. According to the experiments of Dalton and W. Henry the continued passage of electric sparks transforms olefiant gas into a double volume of hydrogen the carbon being separated. Mar-chand observed that at a red heat olefiant gas is decomposed into carbon and marsh gas and that at a white heat carbon aud nearly pure hydrogen are obtained.More recent experiments of Magnu@ have proved that on passing olefiant gas through a red-hot tube about 90 per cent. of the gas are obtained in the form of marsh gas containing a little undecomposed olefiant gas and a small portion of hydrogen; the rest of the gas together with the excess of the carbon is converted into a tarry substance consisting chiefly of liquid and even of solid hydro-carbons. At a white heat according to Magnus olefiant gas furnishes the double volume of almost pure hydrogen gas. Quite recently the decomposition of olefiant gas by the spark- current of the Ruhmkorff coil has been effected by Quet.? On heating by the battery a platinum coil in olefiant gas we observed at once a considerable separation of carbon which was deposited on the sides of the glass tube.The volume of the gas being scarcely changed it was obvious that the principal effect consisted in the transformation of olefiant gas into marsh gas. With the electric arc the decomposition went further. Together with a separation of carbon an expansion chiefly in the com-mencement of the experiment was observed which in the course * Pogg Ann. XC 1. .t Compt. Rcnd. XLVI 1213 DECOMPOSITXON OF GASEOUS COMPOUND% of 10 minutes had reached a maximum; the deaampmition how-ever was not complete 23 C.C. furnished 40 e.o ga~,which did not expand any further. Perfectly similar results were obtained by the spark-current.The spark traverses the gas with a pale reddish light gradually changing to violet A considerable amount of carbon separates in filaments and the current is soon interrupted by a bridge of carbon being thrown from point to point. The volume of the gas in the commencement of the experiment rapidly expands but gradually the rate of expansion becomes very slow ;after 20 or 25 minutes a maximum is reached. 7 C.C. of dry olefiant gas furnished in 25 minutes 12.25 C.C. of gas. By perfect decomposition the double volume should have been obtained. The residuary hydrogen had a peculiar disagreeable odonr and burned with a slightly coloured flame. These experiments shoG that the spark-current decomposes the gas at once into carbon and hydrogen.Marsh gas being so much more stable than olefiant gas we should not have been sur-prised to observe in the first stage of the experiment the elimina- tion of marsh gas. In this case however a considerable quantity of carbon should have been deposited before the volume of the gas commenced to increase. This effect was not observed. SULPHUROUS ACSD. Sulphurous acid gas is decomposed by the incandescent iron coil with the greatest facility. The reaction would be too powerful unless the number of elements were reduced to 10;even then the iron burns with a dazzling bluish-white light and splendid scintil- lation a mixture of sulphide and sesquioxide of iron being pro-duced. 48 C.C. of sulphurous acid gas were reduced in an instant to 10 C.C.The experiment had to be interrupted in order to preserve the tube; the residue was pure sulphurous acid. The spark-current traverses dry sulphurous acid gas with a bluish light. The action is very slow 11C.C. of gas after one hour and a half had become 10 c.c.; after 8 hours the volume was reduced to 4 C.C. During this time a yellowish-brown substance had been deposited on the sides of the glass tube in the proximity of the poles collecting in little drops as long as the glass was gently warmed by the passage of the current and solidifying in the cold to an amorphous mass of a somewhat lighter colour. The residuary gas consisted of pure sulphurous acid ; the brown BUFF AND HOFMANN ON THE substance was found to be a compound of anhydrous sulphuiic acid and sulphur.On addition of water sulphur was separated in flakes and the solution contained free sulphuric acid. Sulphate of mercury could not be traced TLc cliage had obviously been- 3 so,=s+z so, the reaction being the converse of that which is observed wheE sulphur is alloved to act for some time upon anhydrous sul- phuric acid in sealed tubes at the common temperature. The browu substance resembled the similarly coloured but imper-fectly examined product which Vogel obtained many years ago by the action of anhydrous sulphuric acid upon sulphur. When the spark-current is passed through a dry mixture of sulphurous acid and oxygen the volume of the gas is slowly diminished and the sides of the tube become coated with a crystalline deposit of anhydrous sulphuric acid.SULPHURETTED HYDROGEN. According to the experiments of Sir H Davy this gas is decomposed into its constituents by electrically incandescent pla-tinum wire; more slowly by the electric spark. When the iron coil was heated in dry sulphuretted hydrogen we found that a quarter of an hour was by no means sufficient to decompose from 30 to 40 C.C. of the gas. The original volume had not changed but the gas still contained appreciable quantities of sulphuretted hydrogen. The decomposition was more readily effected by the electric arc passing over from iron. This metal burned with evolution of a white light being converted into the sulphide; the unchanged volume of the residuary gas consisted of pure hydrogen.In a quarter of an hour the decomposition of 30 or 40 C.C. was com-plcte. Far less satisfactory results were obtained by the incandescent platinum coil. After it had been glowing for a quarter of an hour in 40 C.C. of sulphuretted hydrogen not less than 32 C.C. of t?ie gas remained undecomposed. The spark-current decomposed the sulphuretted hydrogen per-fectly and with facility. The tube became instantaneously coated DPCONPOSITION OF GASEOUS COMPOUNDS. 28’1 with a film of sulphur and after a quarter of an hour not a trace of sulphuretted hydrogen was left. The volume of the gas was not changed. The spark traversed the gas with a pale blue light gradually turning violet. The change of colour in a measure indicated the completion of the experiment.PUOSPHORETTED HYDROGEN. According to theory 1vol. of this gas when decomposed should yield together with phosphorus 14 volumes of hydrogen gas. By the passage of the electric spark Dalton obtained 13 volume of hydrogen; but the experiments of Gay-Lussac and ThBnard of Dumas and of Buff hare proved that the action of incan-descent metals (antimony copper zinc iron potassium) both upon the spontaneously inflammable aiid upon the other variety gives rise to the evolution of 14 volume. Phosphoretted hydrogen is most readily and completely decom- posed by an incandescent coil of iron or platinum and likewise by the spark-current of the induction coil. Unfortunately the ratio which the volume of the gas bears to the hydrogen evolved can only be cxhibited with difficulty since all the methods of preparing phosphoretted hydrogen hrnish It mixed with free hydrogen ;even the gas obtained from phosphide of calcium or from crystallized phosphorous acid is far from being pure.Accordingly phospho- retted hydrogen when decomposed invariably expands but the theoretical volume is scarcely cver reached. In order to obtain definite results it is necessary to determine the amount of free hydrogen before effecting the decomposition of the phosphoretted liydrogen. This may be done by shaking the gas over mercury with sulphate of copper or better with chloride of lime; the residue consists of pure hydrogen. The complete decomposition of 30 or 40 C.C. of phosphoretted hydrogen either by the incandescent iron coil or by the electric arc passing over from iron is effected in about.5 minutes. The greater portion of the phosphorus is deposited in the form of a browp powder on the sides of the tube; the residuary gas is no longer affected by sulphatc of copper and burns without evolution of phosphoric acid vapoxrs. Similar phenomena are observed when the decomposition is effected by the incaudescent platinum coil. In this experiment 288 BUFF AND ROFiK4NX ON THE however not a trace of phosphorus is separated a silver-white easily fusible and very brittle compound of platinum and phos-phorus being formed. In consequence of this formation the plati- num wire unless it has been taken of very considerable thickness readily fuses and the experiment has then to be completed by the electric arc.The decomposition of 4 or 5 C.C. of phosphoretted hydrogen is effected by the spark-current in about a quarter of an hour. The spark traverses the gas with a reddish light which gradually becomes violet. The volume rapidly increases and the phosphorus Reparates in the amorphous condition. For an experiment of this kind the phosphoretted hydrogen was generated from pure crystallized phosphorous acid. 39%C.C. of this gas when treated with a solution of chloride of lime left 2% C.C. of hydrogen. Accordingly the crude gas contained 93.7 vol. per cent. of pure phosphoretted hydrogen. 5-4 C.C. of the impure gas containing 5*06 C.C. of pure gas furnished after 15 minutes 7-9 C.C.of hydrogen which was not further expanded by the continuation of the spark-current. According to theory (1.5 x 5.06)+0*34= 7-95 C.C. should have been obtained. HYDROCHLORIC ACID. The incandescent iron coil or the electric arc issuing from iron decomposes this gas pretty quickly; the tube becomes filled with white fumes of protochloride of iron and after 5 minutes the ori- ginal volume is reduced to nearly one-half; but it is difficult even by long-continued action to decompose the last traces of hydro-chloric acid; and the residuary volume although apparently one- half of the original volume invariably undergoes a slight contraction upon injection of water. The decomposition is sufficiently complete for a lecture experi- ment but it can scarcely be recommended for this purpose since the composition of 'hydrochloric acid may be exhibited much more rapidly and conveniently by allowing a sodium pellet to rise through the mercury and by shaking the gas with the amalgam formed upon the surface.The spark-current of the induction-coil may be passed through hydrochloric acid gas for a long time without producing any apparent effect. Ultimatgly a slight diminution of the volume is DECOMPOSITION OF GASEOUS COMPOUNDS. observed the surface of the mercury in the tube becoming coated with a thin film of the protochloride. FLUORIDE OF SILICIUM. The incandescent coil of iron or platinum as well as the electric arc is without any perceptible effect upon this gas. The spark- current traverses the gas with a pale blue light.No change of volume waa observed after the lapse of an hour. VOL XIT.
