Borshchevich L. Anodic Reactions in the Solutions of Chromium(III) Salts

The kinetics and mechanism of the processes of water molecules and Cr3+ cations anodic oxidation on the platinum electrode in acid medium. Examination of the mechanism of anodic reactions on the platinum electrode in the solutions of chromium (III) salts. Cyclic and stationary voltamperometry with linear sweep, inversion voltamperometry, spectrophotometry, quantum-chemical semiempirical methods. For the first time it has been determined the nature of the anion and cation catalytic effects on the reaction of water molecules electrooxidation in the diluted solutions of mineral acids. That allowed us to ascertain the autocatalytic nature of the reaction of oxygen deposition and to define concretely possible stages of the process of Cr3+ cations electrooxidation. The results of the investigation can be scientific base for forecasting of electrochemical properties of electrolytes on basis of mineral acids and development of new technologies of electrochemical synthesis of organic and inorganic compounds.
