Book excerpt: The decomposition of Ag2O dissolved in KOH solutions was studied; effects of temperature, light, KOH concentration, Ag2O concentration, and additives on this decomposition were measured. At least two mechanisms are involved but the precise nature of these mechanisms is still unknown. Overvoltages for anodic and cathodic zinc electrode processes were measured by different methods. The presence of additives in the electrolyte had little effect on these overvoltages but overvoltages were markedly affected by KOH concentration and temperature. Amalgamation improved performance of the Zn electrode but this effect decreased with decreasing temperature. Ag contamination adversely affected cathodic Zn electrode processes. It appears that the beneficial effects of additives to the electrolyte are related to the presence of carboxyl groups and that the beneficial effects of additives to the Zn electrode are related to their wetting ability.
