The value of decrease in the strength of hydrophilic materials (alkalinehalide
crystals and polymers) under the influence of solutions of different
electrolytic composition is compared with the structural and thermodynamical
characteristics of water–salt systems reflecting the energy of interaction
between these salts and water. As revealed, the weaker ions of
electrolyte bond water (the greater coefficient of water activity) the
stronger effect of the adsorption decrease of the strength manifests itself.
The mobility of water molecules or the intensity of their translational
movement in the immediate vicinity of hydrated ions is determining factor
in the realization of the effect of material softening.
