Kinetics of the redox interactions of thiourea and its N-substituted derivatives with manganese(III) complex of 2,2'-bipyridine has been investigated in aqueous solution by stopped-flow technique in the acid range +>, 0.10-0.50 mol dm-3 at I=1.0 mol dm-3 (NaClO4) and at 30 deg C.A rapid initial increase in absorbance is followed by a slower decay of the formed species for all the four thioureas.Both the reaction steps are analysed and an inner sphere mechanism has been proposed for these reactions.The reactivity order for these thiourea derrivatives is: ptu>tu>mtu>atu, and this bears a consequence to their substituent effects.

Redox titrations of P(III), Sb(III), As(III), Fe(II), Sn(II), thiourea, hydrazine and their substituted derivatives and of ascorbic acid have been carried out, both potentiometrically and visually, in fused monobromoacetic acid as a solvent and KBrO3, KIO3, K2Cr2O7, KMnO4, K3Fe(CN)6 and ICl as oxidants.The redox reactions of thiourea, hydrazine and their substituted derivatives and of ascorbic acid have been successfully utilised for the estimation of these compounds at 60+/-0.5 deg C.Fused monobromoacetic acid is being introduced as a very good non-aqueous solvent for such redox titrations.
