Abstract
Enthalpies of solution of CaCl2 in aqueous mixtures of methanol, ethanol and propan-1-ol have been measured over the entire range of mixed-solvent compositions. Plots of the standard enthalpy of solution against composition exhibit a maximum in the water-rich region and a minimum in the alcohol-rich region. Enthalpic pair-interaction coefficients have also been calculated: these were found to be positive for electrolyte–alcohol pairs in water and negative for electrolyte–water pairs in alcohols.Keywords
