Solute—solvent interactions and dissolution of some sparingly soluble silver salts in various solvent systems

Abstract

Values for the solubility product of silver salts in aqueous, non-aqueous and mixed solvent systems have been collected and analysed in the light of electrostatic as well as solute—solvent interaction effects on the dissolution processes of the silver salts. Standard Gibbs transfer energies derived from the change in the solubility product value are also examined. The results show that solute—solvent interactions rather than electrostatic effects associated with the change in dielectric constant are largely responsible for the changes in the value of solubility product with the composition of the solvent mixtures.
