Dissolution enthalpy of NaI in water–alcohol mixtures at 288.15 and 308.15 K. Enthalpy of interaction in electrolyte–alcohol–water systems

Abstract

The enthalpy of NaI solution was determined in water mixtures with methanol, ethanol, propanol, and isopropanol in the entire range of mixed-solvent concentration at 288.15 and 308.15 K, and in water mixtures with s-butanol and tert-butanol in the range of 0–5 mol% alcohol at 308.15 K. The dependence of [Formula: see text] on solvent composition was studied. The enthalpic pair interaction coefficients h EN for NaI–alcohol in water and NaI–water in alcohols were determined, and the effect of temperature on h EN values in the systems under study was analyzed.
