A Zinc Nitrate–Calcium Nitrate–Water System: The Solubility of Solids and the Density of Liquids in a Wide Range of Temperatures

The equilibrium phase diagram of the Zn(NO3)2–Ca(NO3)2–H2O system at 251.85, 262.35, and 288.15 K was studied by the isothermal solution saturation method and wet residue analysis. Densities of ternary Zn(NO3)2–Ca(NO3)2–H2O solutions were measured at 298.15–321.35 K. For some solutions, pH measurements were provided at 298.15 K.
