Abstract
Abstract Conductance data for alkali metal chlorides and ammonium chloride in 1,2-dimethoxyethane (DME)–water mixtures (14.00<dielectric constant<56.76) at 25 °C are reported in the concentration range 0.0001–0.06 mol·dm−3. The data have been analyzed by Fuoss (1978) conductance–concentration relation. Preferential solvation of cations by water does not show systematic trend depending on the cationic size. Walden product variations indicated the complex dependence of conductance of alkali metal cations on solvent sorting and structural effects. The energy (Es) values suggest that alkali metal cations and chloride ions in majority exist as contact pairs in these solutions.
