Oxidation of Sn(II) in methanesulfonate electrolytes in presence of antioxidants

The influence of copper(II) ions and some aromatic organic compounds on the oxidation of Sn²⁺ ions in the methanesulfonate electrolyte was studied.     

Chromium Electrodeposition Kinetics in Solutions of Cr(III) Complex Ions

An equation of polarization curve for electroreduction of Cr(II) ions as intermediates in electrolysis of aqueous solutions of Cr(III) complex ions is deduced and analyzed. Kinetic parameters for the discharge of Cr(II) ions are determined. The theoretical results are compared with experimental data obtained from chromium deposition on a rotating disk electrode from Cr(III) solutions containing formate and oxalate.
