✦ Synopsis

Two types of solvent particles resident on the electrode surface have been considered: (1) associates of water molecules freely oriented aIong the electric field and (2) chemisorbed water dipoles oriented with the oxygen atom towards the metal surface. On the basis of this model, a semi-quantitative interpretation has been given to the dependence of the differential capacity of the dense layer on the electrode charge. It has been shown that a change in this dependence, when passing from mercury to gallium, can be described assuming the energy of interaction of chemisorbed water dipoles with the metal surface to increase.
