Double-layer studies in ethanolic solutions. Part 1.—Structure of the mercury/ethanol interface in the absence of specific adsorption

Abstract

Differential capacity against electrode potential data are presented for the mercury/ethanol interface for a variety of 1 : 1 electrolytes at 25 °C in order to determine the effect of simple ions on the inner-layer capacity. Interfacial properties were studied in more detail as a function of both concentration and temperature with NaClO₄ as electrolyte. It is concluded that ionic specific adsorption is negligible for this electrolyte. The properties of the inner layer are examined within the context of the three-state model, and a comparison made with data obtained earlier for the Hg/methanol interface.
