Thermodynamic Properties of Inorganic Salts in Nonaqueous Solvents. II. Apparent Molar Volumes and Compressibilities of Divalent Transition-Metal Perchlorates in Acetonitrile

The densities of divalent transition-metal perchlorates in acetonitrile have been measured at (288.15, 293.15, 298.15, 303.15, 308.15, 313.15, and 323.15) K. From these densities, apparent molar volumes, V Φ , and partial molar volumes of the salts at infinite dilution, , as well as the expansibilities, , have been evaluated. Moreover, the apparent molar isenotropic compressibility, K S, Φ , of transition-metal perchlorates in acetonitrile have been determined from a sound velocity measurement at T = 298.15 K.
