Abstract: A geometric-analytical method has been proposed for the study of solubility isotherms in three-component systems with two salts and a solvent, based on the mass balance of the salt components. Equations have been derived from the diagram of the mass of the equilibrium solid phase vs. the composition, which can be used for the construction of the solubility isotherm in a system with simple eutonic and for the finding of the eutonic point coordinates in such a system without the use of chemical analysis. The method was tested on the KCl—KH₂PO₄—H₂O system and applied to study the solubility isotherm at 0°C in the KCl— K₂H₂P₂O₇—H₂O  system.
