Conductometric study of potassium chloride in ethylene glycol + water mixtures at different temperatures

Molar conductivity of KCl solutions in ethylene glycol + water mixtures (wEG = 0.10, 020, 0.30, and 0.40) was measured at T = (278.15, 288.15, 298.15, and 308.15) K. The values of limiting molar conductivity, association constant, and distance parameter were calculated using the low concentration Chemical Model (lcCM). In this paper the values of Walden product, as well as the standard thermodynamic quantities for the association reaction at T = 298.15 K were presented. Changes in these quantities as a function of changes in the composition of the mixed solvent have been discussed.
