Potentials of the chloramine-T—sulphonamide system have been found to be real redox potentials. With an increase in pH, the oxidation potential decreases. Depending on the pH of the solution, the oxidation of hydrogen sulphide by chloramine-T yields varying proportions of sulphur and sulphate. Reagents like osmic acid, sodium tungstate and sodium molybdate are also found to affect the ratio of sulphur to sulphate, formed by the oxidation of hydrogen sulphide.

A complete explanation for the observed results cannot be based on the effect of pH on the redox potential, as these reagents do not alter the potential. The specific effect of these reagents is probably due to their influence on dihydrogen sulphoxide, the primary product of oxidation of hydrogen sulphide.
