The corrosion of pure and silver-containing lead anodes in electrolytic zinc deposition has been studied under various compositions of electrolytes. The anode potential observed when the bath containing 60g/l zinc increases with increasing the acidity ranging from 50 to 200g/l. On the other hand, anode potential decreases with increasing silver content in the lead anode, irrespectiveof the compositions of electrolytes. The amount of anode slime increases with increasing acidity unless the silver content of lead anode exceeds 0.5%; above this the change is so small and almost negligible. The lead content of cathode zinc is proportional to the amount of anode slime.
From these results, some considerations can be made on the relation of anode potential, the amount of anode slime, distribution of lead in cathode zinc, and the lead content of zinc deposit.
