Titanium(III) species, generated from cathodic reduction of titanium(IV) sulphate using a perforated cylindrical copper cathode under nitrogen cover, have been characterised by UV-visible spectra and by determination of redox potential of Ti(IV)-Ti(III) couple. Redox titrations of chloramine T, chloramine B, bromamine B, bromamine T, dichloramine T, dichloramine B, dibromamine B and dibromamine T with titanium(III) sulphate by volumetry with both visible and potentiometric end points, have been carried out. The monohalo- and dihalo-sulphonamides undergo 2 and 4 electron reductions respectively. These halo-sulphonamides have been used as back titrants for establishing the probable number of electrons involved in the titanium(III) sulphate reduction of certain typical compounds like hydroxylamine, cyclohexanoneoxime and p-nitrotoluene. Utility of titanium(III) as a reductant in the electro reduction processes and ih analytical and kinetic studies have been-highlighted.
