Solubility in the NaCl-NH4Cl-KCl-H2O system

This is the first study of solubility in the NaCl-NH4Cl-KCl-H2O four-component water-salt system at 25, 50, and 75°C. Phase fields of individual salts and potassium and ammonium chloride solid solutions were demarcated. Experimental data were used to develop a mathematical model of the K+, Na+, NH 4 + /Cl−, Cr2O 7 2− -H2O five-component reciprocal system, which includes the title four-component system.
