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.
