Solvent adiabatic compressibility determination at conditions of solution entro-py stability in connection with ionic hydration in electrolytes solutions
The strict approach to determination of solvent adiabatic compressibility at conditions of solution entropy stability has been considered. Generally, the apparent adiabatic compressibility of permeate has been shown to be not equal strictly to the derivate on the pressure from apparent molar volume of permeate under solution entropy stability. Using the given approach, the equation for both the hydration numbers and hydrated complexes adiabatic compressibility determination has been obtained by the thermodynamically correct way. Hydration parameters of the sodium, potassium, magnesium and calcium chlorides as well as the sodium and magnesium sulfates have been determined.
