Аннотация: The structure of charged phase interfaces between mechanically renewable Sn- and Pb-electrodesand LiClO solutions in acetonitrile (AN) with different concentrations was studied by the impedancemethod and cyclic voltammetry. The intervals of the potentials at which these electrodes could be consideredin good approximation as ideally polarizable were established. The zero-charge potentials were estimated tobe and V (with respect to aq. SCE) for the Sn- and Pb-electrodes, respectively. The experimentalcapacitance–potential dependencies were shown to be in good agreement with the classic Gouy–Chapman–Stern–Grahame model. The correlations of the differences between the experimental potentials at zero andstrongly negative charges on the electrical double layer with the difference between the vacuum work functions of these metals were considered and analyzed. The results obtained in AN solutions were compared withthe data for aqueous solutions of surface-inactive electrolytes. It was shown that these metals should be classified among lyophobic systems similar to mercury and some other mercury-like sp-metals according to thecharacter of their interactions with AN and H O molecules.
