The volume change for the dissociation of telluric acid

摘要

The hydrolysis constants of telluric acid were determined by potentiometric titrations at 25°C andI=1.0 mol kg−1NaClO4. Using these results the partial molar volume change according to the dissociation reaction Te(OH)6(aq)⇌ TeO(OH)5(aq)−+H(aq)+was measured densitymetr
