Abstract
Water sorption isobars, isochores and isotherms for CaCl2 confined to a microporous silica gel appear to differ from those measured for meso porous host matrix. The sorption equilibrium was found to be of the bi variant nature typical for liquid salt solutions. No indication for so lid hydrate formation was recorded The results obtained evidence a sig nificant change in the thermodynamic properties of the solution due to its confinement to the micropores. This change is qualitatively discu ssed on the basis of the classical model of strong electrolyte dilute solutions.
