ABSTRACT

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, V1/4 , and partial molar volumes of the salts at infinite dilution, V1/4 0 , as well as the expansibilities, RV 0 , have been evaluated. Moreover, the apparent molar isenotropic compressibility, KS,1/4 , of transition-metal perchlorates in acetonitrile have been determined from a sound velocity measurement at T ) 298.15 K.
