Abstract

Apparent molar heat capacity, Cp,f, and apparent molar volume, Vf, are valuable thermodynamic quantities in the study of solute-solvent interactions and chemical reactions in aqueous solutions. Work in our laboratory1-3 has demonstrated that fixed-cell differential scanning calorimetry (DSC) and vibrating-tube densimetry can provide sensitive and accurate data for calculating Cp,f and Vf. We have recently collected data for solutions of copper(II) nitrate, nickel(II) nitrate, and zinc(II) nitrate. As for most compounds, there is a lack of Cp,f and Vf date for these heavy metal nitrates. Our measurements will allow calculation of Cp,f and Vf.
