ABSTRACT
Apparent molar volumes V/ and apparent molar heat capacities Cp;/ were determined for aqueous solutions of barium nitrate Ba(NO3)2 at molalities m=(0.0025 to 0.2) mol.kg-1, at T =(278.15 to 393.15) K, and at the pressure 0.35 MPa. Our V/ values were calculated from densities obtained using a vibrating-tube densimeter, and our Cp;/ values were obtained using a twin .xed-cell, power-compensation, di.erential-output, temperature-scanning calorimeter. Our results were .tted to functions of m and T and compared with values from the literature.
