Isohydric sections of water–salt systems for solving various problems

Variant uses of phase-field boundaries in isohydric sections of water–salt systems of various complexity are considered for solving applied problems. The major advantages of isohydric sections in studies of systems are shown in the context of determination of compositions of all phases that are formed from initial component mixtures (ICMs) of arbitrary composition in the equilibration, design, and imaging salt preparation processes. The usefulness of the simplex method of converting coordinates and the straight-line equation is shown for the needs of physicochemical analysis of water–salt systems of any complexity.
