摘要:
The electrical conductivities of solutions of nickel chloride in ethylene glycol and glycerol have been measured at 25°C at concentrations within the range 0.001 to 0.5 mol dm−3. The results are consistent with the Debye-Hückel-Onsager theory at low concentrations, and values of the molar conductivity at infinite dilution have been obtained by extrapolation. Values for the ionic conductivity of the doubly charged nickel ion are deduced, for these solvents, using previously measured values for the chlorine ion, whence the ion mobilities of nickel in ethylene glycol and glycerol have been calculated. The results indicate that, as in aqueous solutions, this doubly charged ion has a lower mobility than singly charged ions of the same radius, but that the effect is more marked in ethylene glycol and even more so in glycerol.
