Abstract
The formal redox potential of the Ti(IV, III) couple has been determined at 25 °C in 1 M HCl, 2 M NaCl aqueous medium, by emf measurements of a junction-free cell with glass and mercury electrodes. Ti(III) and Ti(IV) concentrations were changed by controlled electrolysis. The mean value of the searched formal potential, in a large range of total titanium concentration, is 9 ± 1 mV against the molar hydrogen electrode in the same ionic medium.
