Abstract
Electrolytic conductivities of potassium halides KX X = Cl− Br− I− have been investigated in 10 20 and 30 mass glycerol + H2O mixtures at 2980 3080 and 3180 K The conductance data have been analyzed by the Fuossconductance–concentration equation in terms of the limiting molar conductance Λ0 the association constant K A and the distance of closest approach of ion R The association constant K A tends to increase in the order 10 mass 20 mass 30 mass glycerol + water mixtures while it decreases with temperature Thermodynamic parameters ΔH 0 ΔG 0 and ΔS 0 are obtained and discussed Also Walden products Λ0η are reported The results have been interpreted in terms of ion–solvent interactions and structural changes in the mixed solvents
