Solvation and partial molar volumes of some transition metal cations in N, N-dimethylacetamide, triethylphosphate and acetonitrile

Densities of divalent transition metal perchlorates in N, N-dimethylacetamide, acetonitrile, and triethylphosphate have been measured over the whole composition range at 20, 25 and 30 °C. From these densities apparent molar volumes and partial molar volumes of the salts at infinite dilution have bee...

Description
Summary:Densities of divalent transition metal perchlorates in N, N-dimethylacetamide, acetonitrile, and triethylphosphate have been measured over the whole composition range at 20, 25 and 30 °C. From these densities apparent molar volumes and partial molar volumes of the salts at infinite dilution have been evaluated and used to determine the respective ionic volumes of the solvated cations. Factors controlling the partial molar volumes of the solvated cations are discussed.
