Abstract
It is voltammetrically found that a covering film forms on copper in S2–-ion-containing acetate media. It follows from thermodynamic equilibria, crystallographic parameters, and x-ray spectra of the metal and its compounds that the overall anodic process is composed of two separate processes and yields Cu2S and Cu2O. The reaction order in S2– ions (∂log i/∂log C i)ΔE = constis 0.37. Possible stages of the electrode process are suggested.
