Electrical conductance of alkali chlorides in mixed solvents : Methanol + carbon tetrachloride and methanol + 1,4-dioxane at 298.15 K

摘要

Conductance measurements for selected alkali metal chlorides,MCl (M+ = Li,Na,K) are performed in the binary mixtures of methanol with carbon tetrachloride and 1,4-dioxane at 298.15 K.The limiting equivalent conductance (LAMBDA0),the association constant (K_A),and the Walden products (LAMBDA0 eta0) for the three salts are evaluated at all the mole fractions of the solvent mixtures using the 1978 Fuoss conductance-concentration equation.Analysis of data indicates presence of strong association of the electrolytes in the solvent mixtures studied here.The results have been discussed and interpreted in terms of ion-solvent interactions and structural changes in the mixed solvent systems.
