Abstract

Transport processes that take place during the anodic dissolution of a metal accompanied by the formation of negatively charged intermediate particles are theoretically considered. Distributions of the component concentrations and electric potential in the diffusion layer during the quasi-equilibrium decomposition of intermediate particles are calculated. Analysis predicts the existence of the admissible concentration limit of anions depending on the stability constant of intermediate particles. The effect of the stability constant on the potential distribution within the diffusion layer and on the shape of voltammetric curves of the process is found to be complex.
