The reaction between HBrO2 and bromate was studied in sulfuric acid solution. From the spectral dependence of the absorbance in the region from 400 to 600 nm it is concluded that BrO2 is an intermediate of the reaction. From the maximum concentration of BrO2 the equilibrium constant of the BrO2/Br2O4-equilibrium is evaluated; furthermore, a value for the ratio of the rate constants for the HBrO2/BrO3--reaction and the disproportionation reaction of HBrO2 is given.

Abstract The reaction between Ce3+ and bromate was studied in sulfuric acid solution using a dual wavelength spectrometer. From the spectral dependence of the absorbance in the region from 450 to 600 nm it is concluded that BrO2 is an intermediate of the reaction. The kinetics of formation and decay of BrO2 is compared to theoretical models.
