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.
