Abstract: A method has been proposed for the study of solubility isotherms in three-component systems with two salts and a solvent generalizing the geometric-analytical method described earlier. Computational programs have been formed to construct the solubility isotherm and to identify the equilibrium solid phases using the composition of phase complex and the mass of equilibrium solid phase as the input. The computational procedure involves iterative elimination of adhered mother liquor and may be modified to solubility investigation of maximum precision. The method was tested on the K₂SO₄-MgSO₄-H₂O system and applied to the study of the solubility isotherm at 25 °C in the glycine-H₂SeO₃-H₂O system. During this application, new compound gly . H₂SeO₃ was synthesized.
