Abstract
The current yield of the electrolytic preparation of concentrated solutions of ammonium peroxodisulphate was found to decrease with decreasing degree of saturation of the starting solution. It is therefore preferable to work with a starting solution of maximum allowable concentration with respect to the given temperature of electrolysis. As the temperature is increased, the current yield decreases progressively even if starting solution of maximum allowable concentration has been used; at the same time, the voltage on the electrolytic cell somewhat decreases. The observed effect of temperature on the current yield is a resultant of its effects on a number of simultaneously occurring electrochemical and chemical processes in the anode compartment.Keywords
