Re: Bro4 Compound

Chemical compound with a formula Ba(Bro4)2 is barium perbromate.

Synthesis

Attempted syntheses of perbromates were unsuccessful until 1968, when it was finally obtained by the beta decay of selenium-83 in a selenate salt:[4][5]

83SeO42− → 83BrO4− + β−

Subsequently, it was successfully synthesized again by the electrolysis of LiBrO3, although only in low yield.[5][6] Later, it was obtained by the oxidation of bromate with xenon difluoride.[3][7] Once perbromates are obtained, perbromic acid can be produced by protonating BrO−
4.[2]

One effective method of producing perbromate is by the oxidation of bromate with fluorine under alkaline conditions:[2][8]

BrO−
3 + F2 + 2 OH− → BrO−
4 + 2 F− + H2O

This synthesis is much easier to perform on a large scale than the electrolysis route or oxidation by xenon difluoride.
