Application of primitive model of electrolyte solutions for thermodynamic description of ternary system VOSOΛ4-HΛ2SOΛ4-HΛ2O at 298.15 K

Axioms of primitive model of electrolyte solutions are formulated. The model can be considered as one possible models of a real solution enabling to perform thermodynamic description of a solution on the basis of limited number of experimental data. Model applicability to solutions of completely dissociated electrolytes s demonstrated. Calculation of osmotic factors and activity factors of VOSO4 in its aqueous solutions (including oversaturated ones) at 298x15K and calculation of VOSO4x3H2O isotherm of solubility in aqueous solutions of sulfuric and were taken as an example
