Abstract
The adiabatic compression method is used to determine quantitative solvation parameters such as hydration numbers h, the molar adiabatic compressibility of hydrated complexes βhVh, the volume V1h and compressibility β1h of water in ion hydration shells, and several other properties in the temperature range 278.15-323.15 K. Hydration numbers are used to determine the verified activity coefficient of the solvent, γR. The concentration dependence of the coefficient is shown to be a discontinuous function, with the discontinuity point corresponding to the complete solvation boundary.
