The Pitzer ion-interaction model was used for a simulation of the CuCl2-MCl2-H2O (M = Mg, Co) systems at 298.15 K. The necessary thermodynamic functions (binary and ternary ion-interaction parameters and thermodynamic solubility products) were calculated and the theoretical solubility diagrams plotted. A very good agreement was obtained between the calculated and observed data.
