Aqueous Solutions and Water Polyamorphism

From a viewpoint of water polyamorphism, we examined the polyamorphic behaviors of the glass of dilute aqueous solutions, a glycerol-water system and a LiCl-water system, under pressure. The polyamorphic behaviors of aqueous solution are consistent with the water polyamorphism. The solvent water in the glassy aqueous solution is able to be classified as LDA-like or HDA-like solvent waters. A coexistent region of LDA-like and HDA-like solvent waters exists in the polyamorphic diagram of the aqueous solutions, and then the extent of the coexistence region depends on the solute concentration and the solute composition.
