摘要：

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 degreesC. 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. (C) 2004 Elsevier B.V. All rights reserved.
