Oxidimetric determination of thiourea, thiosulphate and sulphite with thallic perchlorate in acid medium

The stoichiometry of the reaction of TIIII with ascorbic acid (H2A) in the presence and absence of chloride ion conforms to TIIII + H2A > TII + 2H+ + A. where A is dehydroascorbic acid. The reaction exhibits complex kinetics and the reactivity of various chlorothallium (III) species decreases in the order of [TIOH]2+ > TI3+ > [TICI]2+ > [TICI2]+ > TICI3 > [TICI4]−. The mass balance relationship was employed to calculate the equilibrium concentration of the chloride ion for evaluation of the rate constants.
