ABSTRACT

Apparent molar volumes and apparent molar heat capacities were determined for aqueous solutions of nickel(II) nitrate, copper(II) nitrate, and zinc(II) nitrate at molalities m 0:01 to 0:5 mol kg-1, and at the pressure p = 0:35 MPa. Solution densities obtained using a vibrating-tube densimeter at T = 278:15 to 368:15 K were used to calculate V/ values. Heat capacity measurements obtained with a twin fixed-cell, differential-output, power-compensating, temperature-scanning calorimeter at T = 278:15 to 393:15 K were used to calculate values of Cp. Our results were then fitted to functions of m and T and compared to literature values.
