Аннотация:The solubility of ozone in solutions of oxalic acid H2C2O4 and potassium nitrate at concentrations up to 1 and 2 M, respectively, is studied at 25°C. The Sechenov constants for these electrolyte solutions are found: 0.081 ± 0.010 and 0.082 ± 0.004 1/M, respectively. The anion-specific parameter in the Weisenberger–Schumpe gas solubility model for oxalate ion is determined: h(C2O4--) = 0.1266 1/M. A set of coefficients is determined using the experimental data from various sources to calculate the density of H2C2O4 solutions as a function of temperature in the range of 5–100°C at solution concentrations up to the saturated concentration at a given temperature.
