My. Skripkin et al., THERMODYNAMIC STUDY OF TERNARY-SYSTEMS RB-TO-CL--H2O AND CS+,MG2+PARALLEL-TO-CL--H2O AT 25-DEGREES-C(, MG2+PARALLEL), Russian journal of applied chemistry, 66(5), 1993, pp. 807-810
The solubility and activity of water in the systems studied were deter
mined experimentally. The solubility isotherms calculated by using Pit
zer's equation from the data on composition of solid phase and water a
ctivity in the ternary systems was shown to be in a good agreement wit
h experimental results. The free energies of formation of rubidium and
cesium carnallites were calculated.
