The kinetics of Tl(III) oxidation of hydroxylamine hydrochloride in 1·0 M H2SO4 at a fixed chloride concentration has been investigated to make a formal comparison of the observed rate with that of hydrazine sulphate. The reaction exhibits total second order kinetics—first order in each reactant. The rate of the reaction depends inversely on the first power of [H+] and [Cl−] suggesting the possible reactive species as TlOH2+. To account for the stoichiometry of the reaction [Tl(III)]: [H2NOH·HCl)=1·5∶1 and the products of the reaction, HNO2 and N2O, two reaction schemes have been proposed.
