Use of Pitzer's model to calculate thermodynamic properties of aqueous electrolyte solutions of Na2SO4+NaCl between 273.15 and 373.15 K
Fitter's model has been used to calculate various thermodynamic properties of NaCl-Na2SO4-H2O system. A methodology taking into account enthalpy and solubility data has been proposed. This leads to the proposal of a unique set of parameters allowing simultaneous representation of dissolution enthalpies, activity coefficients and solubility data in binary and ternary systems.
