Abstract

The interaction of uranyl (IV) ion with benzoic acid have been investigated pHmetrically in different dielectric environment of 10%, 20%, 30%, 40% and 50%, dioxane- water mixtures. Bjerrum’s potentiometric titration as adopted by Calvin and Wilson have been used to determine proton –ligand and metal-ligand stability constant using Irving-Rossoti’s expression. The variation in values of n, n A, log K1 and log K2 at different percentage compositions of dioxane-water shows favourable effect on complexation equilibria.
