ABSTRACT

Conductance measurements of tetramethylammonium bromide (Me4NBr), tetraethylammonium bromide (Et4NBr), and tetrapropylammonium bromide (Pr4NBr) solutions in 2-butoxyethanol (1) + water (2) mixture with 0.20, 0.40, and 0.60 mass fraction of 2-butoxyethanol were reported at (298.15, 303.15, 308.15, and 313.15) K. The experimental values of electrical conductances are analyzed using the 1978 Fuoss conductance concentration equation to obtain values of limiting molar conductance (?0), ionic association constant (KA) and the association diameter (R). The values of KA and R obtained for these three salts, namely, tetramethylammonium bromide, tetraethylammonium bromide, and tetrapropylammonium bromide suggest a weak electrostatic ion solvent interaction. Besides, they exist as free ions in all the solvents compositions and temperature range covered in this study. The Walden products for the ions show perceptible variations under increasing temperature and in different solvent composition.
