Comparative analysis of solubility in CuCl-MCl-H2O systems at 25°C (M+ = Li+, Cs+, NH 4 + )

Solubility in the ternary system CuCl-NH4Cl-H2O at 25°C was determined by the method of isothermal lifting of oversaturation. A comparative analysis of solubility in this system and the previously studied systems CuCl-MCl-H2O (M+ = Li+, Na+, K+, Cs+) was made. The results obtained were interpreted in terms of competition between hydration, association, and complexation processes in water-salt systems.
