Electrolytic conductivities of some sodium salts (NaI, NaSCN, CH 3 COONa) have been studied in 0, 25, 50 and 75mass% ethane-1,2-diol+methyl alcohol mixtures at 293.15, 298.15 and 303.15K. The limiting molar conductivity (Λ°), the association constant (K A ) and the distance of closest approach of ion (R) have been evaluated using the Fuoss conductance equation (1978). The association constant (K A ) decreases with temperature while it tends to decrease in the order: 0mass%>25mass%>50mass%>75mass% ethane-1,2-diol+methyl alcohol mixtures. Thermodynamic parameters ΔH°, ΔG° and ΔS° along with the Walden products (Λ°η) are obtained and discussed. The results have been interpreted in terms of ion–solvent interactions and structural changes in the mixed solvents.
