The surface phase at the ideal polarized mercury electrode: I. General thermodynamic and hydrostatic considerations of ionic adsorption⋆

摘要: Summary A thermodynamic derivation is presented for temperature and pressure coefficients of the surface tension at ideal polarized electrode in systems mixed common ion symmetrical strong electrolytes constant ionic strength. Based upon these coefficients, an evaluation partial molar phase entropies volumes suggested. The treatment requires a convenient transformation system state variables adequate choice conventions compatible with concept electrochemical inner diffuse layers. complementary insight into problem phases gained from consideration hydrostatic electrostatic forces stresses boundary liquid metal electrode. Expressions yielding potentials are derived, revealing non-autonomy layer as regards adjacent phases. Finally, relevance given expressions entropy solvent relation to some isotherms specific adsorption, discussed.
