摘要：

Measurements of densities of solution of AgNO3 and Ca(NO3)2 in the mixed solvents water-methanol and water-acetonitrile were carried out at 25-degrees-C and the partial molar volumes V2 infinity of these electrolytes were determined by taking account of the concentration dependence of the apparent molar volumes predicted by the Debye-Huckel theory. The ionic partial molar volumes of Ag+, Ca2+, and NO3- were evaluated and compared with those of other ions in the two mixed solvent systems. The solvent composition dependence is more remarkable in water-acetonitrile than in water-methanol, and characteristic behavior was observed for Ag+ and Ca2+ ions in water-acetonitrile system.
