Аннотация: A comprehensive data set of thermodynamic and calorimetric properties of calcium nitrate aqueous solutions, including the heats of dilution, heat capacity, and phase equilibria in a wide temperature and concentration range is thoroughly collected and critically reviewed. A temperature-dependent Pitzer–Simonson–Clegg model is proposed to describe reliably the properties of liquid phase as well as solid–liquid (SLE) and vapor–liquid (VLE) equilibria, including metastable ones, over T = (243.15 to 425.75) K and up to x(Ca(NO3)2) = 0.3. Improved accuracy is obtained as compared to that of earlier models along with incorporating many diverse experimental data types simultaneously.
