Аннотация:The mass transfer during the electrochemical dissolution of metals with the participation of electrolyteanions and the formation of stable anionic complex is analyzed by the example of tungsten anodicdissolution in the alkaline solutions. The distributions of ionic concentrations, partial current densities ofions and potential over the solution layer near the anode are determined as a result of numerical solutionof the problem. The results of numerical solution are compared to the results of analytical solution andexperimental data available from the literature. It is shown that the numerical solution of the problemwith regard for migration, convection and concentration dependences of transport properties of solutionagrees well with the experimental data. A complex role of ion migration in this process is revealed.
