Abstract(1)The solubility product of silver chromate was determined from e.m.f. of the cell,by extrapolation of the function,to x=0 and then m=0. K s.p. in the temperature range of 20° to 40°C is expressed by(2)The molal heat of solution of silver chromate was evaluated from the temperature coefficient of 1n Ks.p. and given by(3)The standard potential of the Ag; Ag3CrO4(s), CrO4−electrode was evaluated from E° = π°Ag;Ag+− k log Ks.p. It is given by(4)The molal free energy change for solution of Ag2CrO4(s) is given by(5)The molal heat, free energy and entropy change of formation of silver chromate from its elements at 25°C were
