Electrolytes. From dilute solutions to fused salts [PDF]

Journal of the American Chemical Society, 1980
Solutions with composition extending continuously from molecular liquids such as water to fused salts are relatively unusual but of considerable interest. Conductance and thermodynamic properties are considered for several examples. New equations for the activities of the respective components represent the data more accurately than previous treatments
