Abstract
Based on the experimental studies of the dissolution of Cr2O3 and CuO in an acidic environment, as well as investigation of the effect of acids, pH, and concentration of anions on the rate of dissolution of the oxides, the nature of the limiting stage is determined which consists in the formation of surface compounds (depending on the acidity of the environment) of the \({\text{MeOH}}_{s}^{{x + }}\) and \({\text{MeHSO}}_{{4s}}^{{x + }}\) types and their subsequent transition into the solution of the electrolyte. The comparative analysis of the dissolution of the oxides of two d metals is performed.
