Abstract

Abstract In order to confirm previous findings relative to the electrolytic evolution of chlorine and oxygen from neutral and alkaline KCl solutions, anodic polarization curves for a platinum electrode in these solutions were plotted from experimental potential measurements. In neutral KCl solutions a decrease in KCl concentration resulted in a shift of the polarization curve into a region of more positive potential values. In alkaline KCl solutions of various KCl concentrations, it was indicated that the activity of surface oxides formed on the anode was an important factor in the kinetics of the electrode reaction.
