摘要：

The solubility of the systems RbCl-MgCl2-H2O, RbBr-MgBr2-H2O and CsBr-MgBr2-H2O have been investigated by the physicochemical analysis method at 25-degrees-C and the formation of carnallite type double salts was established. The Pitzer model is used to calculate the thermodynamic functions needed to plot the solubility isotherms of the systems. The results obtained are in good agreement with the experimental data. The free energies of formation of carnallite and bromcarnallite type double salts from simple salts and the standard molar energies of formation are estimated.
