✦ Synopsis

The electrochemical reduction of the solvated hydrogen ion dissolved in DMSO as HCl was investigated from 25 to 45"C, at different concentrations and ionic strength. Stationary and nonstationary techniques were employed to obtain the kinetic parameters. The results were interpreted with a reaction scheme involving an initial electron transfer as rds, probably followed by an electrochemical desorption step.

Al~traet--Two main views are found in the literature regarding the type of oxide formed on copper anodes in alkaline solutions. The one considers that copper oxidizes to Cu~O and CuO (or Cu(OH),) before oxygen evolution. Mftller is, however, of the opinion that a still higher oxide, Cu~O,, forms. Th
