Abstract

© Pleiades Publishing, Ltd., 2014. © A.G. Davidian, A.G. Kudrev, L.A. Myund, O.S. Khlynova, M.K. Khripun, 2014. The IR spectra of aqueous solutions of MClO4, MNO3, MCl (M = Li, Na), CsCl, and Na2SO4 were measured at frequencies of 5400-7500 cm-1 over a wide concentration range from 0.12 M up to saturation concentrations at 25°C. Chemometric analysis of the experimental data matrix was performed. Regularity was detected in distribution of the IR spectra of the studied aqueous solutions on the the plot of analysis scores by the principal component method depending on the nature of the anion-water interaction. The influence of the nature of the salt anion and cation on the water structure in aqueous electrolyte solutions was demonstrated. The existence and interconversion of the spectral forms of water with changing electrolyte concentration in solution were revealed.
