Temperature-induced change of water structure in aqueous solutions of some kosmotropic and chaotropic salts

Abstract

The hydrogen bond structure of water was examined by comparing the temperature dependent OH-stretching bands of water and aqueous NaClO4, KClO4, Na2 SO4, and K2 SO4 solu-tions. Results called attention to the role of cations on top of the importance of anions determin-ing the emerging structure of a multi-layered system consisting single water rings or multi-ring water-clusters.
