Title: Enthalpies of dissolution of alkali halides in mixtures of dimethyl sulfoxide with water or heavy water

Abstract

The enthalpies of dissolution of cesium fluoride, lithium and sodium chlorides, potassium bormide, sodium and cesium iodides, and tetrabutylammonium bromide were measured by means of calorimetry, and the standard enthalpies of dissolution of all alkali halides (except rubidium halides) in mixtures of dimethyl sulfoxide with water or heavy water at 298.15 K were calculated from the differences of the enthalpies of transfer. It is shown that solvation of alkali halides in the examined mixtures is more strongly affected by the nature of the anion rather than by the nature of the cation. Isotope effects on the enthalpies of solvation of the above-listed electrolytes in aqueous solutions of dimethyl sulfoxide are discussed, and the data obtained are compared with the corresponding data for tributylammonium bromide. 29 refs., 2 figs., 4 tabs.
