Bromaatti

Bromaatti-anioni

Bromaatti (BrO3-) on oksioanioni. Metallin reagoidessa bromihapon (HBrO3) kanssa muodostuu suoloja, joiden nimi on bromaattipäätteinen.[1] Tällaisia suoloja ovat muun muassa natriumbromaatti (NaBrO3) ja kaliumbromaatti (KBrO3).

Bromaatit ovat vahvoja hapettimia ja kuumennettaessa monet bromaatit hajoavat bromideiksi ja hapeksi.[1][2] Bariumbromaattia lukuun ottamatta bromaattisuolat ovat hyvin vesiliukoisia. Bromaatteja voidaan valmistaa bromidisuoloista elektrolysoimalla tai bromin ja hydroksidiliuosten välisellä reaktiolla.[2]
