General description

Potassium bromate (KBrO3) is a colorless solid having trigonal crystals. On heating above 430°C, it degrades and liberates oxygen. It is strongly oxidizing in nature. Its industrial synthesis from potassium bromide via anodic oxidation has been reported. Its quantitative estimation by sensitive flow-injection chemiluminescence method has been proposed. Its standardization has been reported by iodometric titration against sodium thiosulphate (hypo) solution.

Application

Potassium bromate (KBrO3) may be used in volumetric determinations. It may be used as an oxidizing reagent for the oxidation of neomenthol. Kinetics and mechanism of the oxidation reaction has been investigated.

Other Notes

For the in situ production of bromine in TLC; Primary standard for bromometry
