What is "perbromate"

Perbromate \Per*bro"mate\, n. (Chem.) A salt of perbromic acid.

n. 1 (context inorganic chemistry English) The oxyanion of bromine BrO₄^- 2 (context inorganic chemistry English) Any salt (of perbromic acid) containing this ion

In chemistry, the perbromate ion is the anion having the chemical formula . It is an oxyanion of bromine, the conjugate base of perbromic acid, in which bromine has the oxidation state +7. Unlike its chlorine and iodine analogs ( perchlorate and periodate), it is difficult to synthesize. It has tetrahedral molecular geometry.

The term perbromate also refers to a compound that contains the anion or the functional group.

The perbromate ion is a strong oxidizing agent. The reduction potential for the / Br couple is +0.68 V at pH 14. This is comparable to selenite's reduction potential.
