The adsorption of HSO4- (SO42-) and Cl- ions was studied by a radiotracer technique in the course of the formation and dissolution of a copper adatom layer at a rhodized electrode during cyclic voltammetric measurements. It was found that no significant change occurs in the apparent anion adsorption during the formation of the adlayer. The explanation of this observation is presented in the light of experimental results reported in the present and previous papers.
