Infobox references

Sodium bromate, the inorganic compound with the chemical formula of NaBrO₃, is the sodium salt of bromic acid. It is a strong oxidant, mainly used in continuous or batch dyeing processes involving sulfur or vat dyes and as a hair-permagent, chemical agent, or gold solvent in gold mines when used with sodium bromide.

Production

Sodium bromate is produced by passing bromine into a solution of sodium carbonate. It may also be produced by the electrolytic oxidation of sodium bromide.
