Perbromate

As Perbromates refers to the salts of perbromic with the formula - BrO4. The central bromine atom is in the 7 oxidation state and is surrounded tetrahedrally by four oxide ions.

History and production

Despite many attempts to synthesize it was not until late to find a synthetic route for macroscopic quantities perbromate. In 1963, calculations showed that Perbromates principle can not be stable and synthesis experiments were therefore pointless. The first synthesis then used the radioactive decay of selenate with radioactive 83Se:

Also, the electrolytic oxidation of bromate to perbromate described there, however, only with a yield of 2%. Later could be oxidized by bromate with elemental fluorine. This was in spite of experimental difficulties so far to synthesize the best method Perbromates when working with fluorine gas. Meanwhile, it is able to synthesize perbromate by electrolysis of doped diamond anodes of bromide. The product, however, lies in front next to the bromate. The yields are in the lower percentage range.

Properties

Similar to the homologous perchlorate ion is the Perbromation a weakly coordinating anion and a good resonance-stabilized oxidizing agent. Unlike perchlorates is Perbromates but not decompose thermally bromides but react to oxygen delivery to bromate.

Usually the more accessible perchlorate salts are used instead Perbromatsalzen.
