THERMODYNAMICS OF SILVER SALICYLATE IN WATER AND WATER +10, +20, AND +40 MASS PERCENT OF DIOXANE AT DIFFERENT TEMPERATURES

The solubility studies on silver salicylate at different temperatures were made to derive (a) the standard electrode potential of the silver-silver salicylate electrode, (b) the mean activity coefficient of silver salicylate, (c) the dissociation constant of salicylic acid, and (d) the standard thermodynamic quantities, ΔG0t, ΔH0t, ΔS0t, and δC0pt, for the transfer of silver salicylate from the standard state in water to the standard state in water + 10, + 20, and + 40 mass percent of dioxane. The results are discussed in terms of the preferential solvation of the ions. © 1979.
