Mononuclear hydrolysis of titanium (IV) from partition equilibria

Abstract The mononuclear hydrolysis constants of titanium (IV) have been calculated by means of partition data for titanium (IV) between aqueous solutions 0·1 M in perchlorate and organic solvents containing 8-hydroxyquinoline in chloroform and TTA in benzene. The experimental data can be explained in terms of the following equilibria: Since the existence of Ti4+ is ruled out in the pH range 0·5-3, the solubility product of titanium (IV) hydroxide [TiOH]3+[OH−]3 has been determined. The formation constants of the complexes titanium −TTA and titanium-oxine in water solutions have been calculated by taking into account hydrolytic equilibria.
