Spectral and chemical data are presented which show that bromine and bromate ion in acid solution are unstable with respect to, formation of hypobromous acid. At higher concentrations of hypobromous acid, the reaction is reversed, and this species decomposes relatively rapidly to bromine and bromate. Some aspects of the kinetics of these reactions are described, from which deductions are made regarding possible mechanisms of the two processes.

Radiotracer studies with Br82 show that bromine and bromate ion in perchloric acid solution undergo isotopic exchange at a measurable rate. The kinetics of the process suggest that secondary chemical reactions occur, leading to the formation of significant concentrations of hypobromous acid in the system. The isotopic exchange between hypobromous acid and bromine is complete within the time required to separate these species.

The kinetics and stoicheiometry of the decomposition of aqueous solutions of sulphur dicyanide have been studied at temperatures between 0-70 �C and in media ranging from dilute perchloric acid to pH 7. The predominant reaction is nucleophilic substitution at carbon, but in perchloric acid solutions an alternative reaction path has been revealed.
