Activities and Surface Tension of Liquid AgCl ‐ KCl Solutions

Abstract
Thermodynamic properties of liquid solutions were investigated at concentrations of at temperatures of 860°–1000°K by the method of formation cells with chlorine electrode. The partial thermodynamic data of were interpreted by Krupkowski's method and the relations of activity coefficients of both and were obtained. Simultaneously, the surface tension measurements of pure , , and liquid solutions were carried out using the maximum bubble pressure method at temperatures of 734°–1220°K dependent on the composition of investigated solutions and the melting points of pure salts. Using the thermodynamic data of bulk solutions, results of surface tension, and the calculations of the composition of the surface phase of the thickness , the activity coefficients of in this phase were obtained.
