Perbromate

In <a href="/facts/Chemistry/SrNqkGVm">chemistry</a>, the perbromate ion is the <a href="/facts/Anion/wrbwhF3z">anion</a> with the chemical formula BrO−4. It is an <a href="/facts/Oxyanion/0GuWXr6D">oxyanion</a> of <a href="/facts/Bromine/oLfj3C7D">bromine</a>, the <a href="/facts/Conjugate_base/hohgQ07M">conjugate base</a> of <a href="/facts/Perbromic_acid/o9sxbKfC">perbromic acid</a>, in which bromine has the <a href="/facts/Oxidation_state/W53W6s6V">oxidation state</a> +7. Unlike its chlorine (<a href="/facts/Perchlorate/WCC53zS2">ClO−4</a>) and iodine (<a href="/facts/Periodate/y9IRt4t6">IO−4</a>) <a href="/facts/Structural_analog/3aysWSVG">analogs</a>, it is difficult to synthesize. It has <a href="/facts/Tetrahedral_molecular_geometry/583AL1sP">tetrahedral molecular geometry</a>.
The term perbromate also refers to a compound that contains the BrO−4 anion or the −OBrO3 <a href="/facts/Functional_group/GXkSPsjM">functional group</a>.
The perbromate ion is a strong oxidizing agent. The reduction potential for the BrO−4/<a href="/facts/Bromide/bHSfxGk1">Br−</a> couple is +0.68 V at pH 14. This is comparable to <a href="/facts/Selenite_(ion)/wJvsRY2r">selenite</a>'s reduction potential.
