Calorimetrically determined log K, ΔH°, and ΔS° values for the interaction of sulphate ion with H+, Na+, and K+in the presence of tetra-n-alkylammonium ions

Abstract
Log K, ΔH°, and ΔS° values for the interaction in aqueous solution at 25° of SO4 2– with H+, Na+, and K+, and of ClO4 with R4N+(R = Me, Et, and Prn), have been determined using a calorimetric titration procedure. The results indicate that the tetra-n-alkylammonium ions do not associate appreciably with SO4 2–.
