Popis:	The behavior of copper in the active state during the anodic polarization in bicarbonate media is studied. It is shown that the anodic ionization of copper represents a two-stage process with univalent copper as the intermediate. The presence of the latter was confirmed by the RRDE method. The diffusion of bivalent copper is the rate-determining stage, and the equilibrium between copper and its bivalent ions is the potential-determining reaction. It is shown that the conventional method of preparation of bicarbonate solutions for experiments is inadequate; hence, the corresponding conclusions that had formerly been drawn on the oxidation of copper to univalent state are incorrect.
