Abstract
The kinetics of hydrolysis of sulphamic
acid, NH2SO2OH + H2O → NH4HSO4,
have been studied in water, in aqueous perchloric acid solution, and in
acetone-water mixtures. The rate data obtained in water did not give good
first-order plots - a fact attributed to a variation in the degree of
dissociation of sulphamic acid with concentration, and to the production of
hydrogen ions by dissociation of bisulphate ions formed in the reaction - but
in the presence of perchloric acid good first-order plots were obtained. The
rate data for hydrolysis in aqueous acetone (in the absence of HClO4) gave good first-order plots. For
[water]<l mole l-1 the rate constant at 35 �C is independent of
the water concentration and is about 1000 times that in water at the same
temperature. It seems probable that the rate controlling step in aqueous
acetone and also in water involves a unimolecular decomposition of the
zwitterion form of sulphamic acid, namely +NH3 SO3-.
