Stability characteristics of aqueous chloramine-T solutions.

Aqueous chloramine-T solutions in strongly alkaline medium are quite stable even up to 60 degrees . In 0.2-2 M sulphuric or perchloric acid at 25-30 degrees , there is no loss in titre, but in hydrochloric acid solutions > 0-5M, there is a loss in titre which increases with increase in hydrochloric acid concentration.

Estimation of dimethylsulphoxide with chloramine-T.

A rapid and accurate method for the estimation of dimethyl-sulphoxide has been developed based on its oxidation to dimethyl-sulphone at room temperature by chloramine-T at pH 4-4.5. The effect of variables such as the pH, the mode of addition of reagents and the concentration of chloride ion on the extent and nature of oxidation has been studied and optimal conditons for analytical determination of dimethylsulphoxide derived.

Oxidimetric determination of sulphides.

Hypoiodite oxidises sulphides much more rapidly than does iodate under comparable experimental conditions. A procedure is reported for the determination of soluble and insoluble sulphides by oxidation to sulphate with hypoiodite. This is an improvement over Bethge's iodate method.
