Аннотация:Differential capacitance curves and potentials of zero charge are obtained for liquid Cd-Ga electrodes in methanol and propylene carbonate solutions of a surface-inactive electrolyte. It is found that double-layer characteristics of the Cd-Ga electrode differ from those of a Ga electrode both in nonaqueous solutions and in water. The lyophilic nature of the Cd-Ga electrode, relative to methanol and propylene carbonate, is shown to approach that of the In-Ga electrode. In the absence of a metal-solvent chemisorption interaction, the difference between reciprocal "metallic" capacitances for Cd-Ga and Hg electrodes is independent of the solvent nature. The chemisorption interaction between the solvents and Cd-Ga, Ga, and In-Ga electrodes increases with the solvents' donor number.
