Abstract

Abstract: In this paper, we briefly review our researches of concentrated electrolyte solutions by means of proposed phenomenological model. Electrolyte solutions are complex systems with multitude of interactions. However, totality of interactions in solution is reflected in its constitution. The description of solution structure includes all parameters that define short-range ordering of particles, a full description of all possible coexistent vibrationally averaged structures (V- structures). We believe that information about the presence of the concentration ranges with different dominant structures and boundaries may be derived from the solubility polytherm (phase diagram) of the water-salt system. The boundary concentration corresponds to the eutectic composition (EC). In the range of pre-eutectic concentrations the dominant structure is the proper structure of water, ion hydration is the major type of interaction between components. A crystalline hydrate or anhydrous salt crystallizes at reduced temper
