Conductometric study of potassium chloride in ethylene glycol + water mixtures at different temperatures
Zdzisław Kinart, Renato Tomaš
Abstract
Molar conductivity of KCl solutions in ethylene glycol + water mixtures ( w EG = 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 ( Λ °), association constant ( K A ) and distance parameter ( R ) were calculated using the low concentration Chemical Model (lcCM). In this paper the values of Walden product ( Λ °· η ), 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.
