Surface excess entropies and volumes of the mercury-electrolyte interface

Abstract

Further consideration is given to the excess entropies and excess volumes of the mercury-aqueous solution interface. By a quasi-thermodynamic argument the excesses are resolved into the separate contributions of the ions and of the solvent. The latter contribution to both the excess entropy and the excess volume exhibits a pronounced maximum on the negative side of the potential of zero charge which is attributed to a minimum degree of preferred orientation of the solvent modecules at the metal surface.
