Thermodynamic characteristics of the resolvation of K+ and Cl– ions in mixtures of water with aprotic solvents

The solvation of K⁺ and Cl^– ions in water mixtures with aprotic solvents (acetone, acetonitrile, dimethylsulfoxide and dimethylformamide) was studied based on the analysis of primary effects of the medium of K⁺ and Cl^– and the chemical Gibbs energies of transfer of these ions from water to the mixed solvents at 298.15 K obtained from Volta potential differences.
