Description of Gold(III)-Bromide Powder
Gold bromide is an inorganic compound with the chemical formula AuBr3. It is a Lewis acid, that is, a chemical species which accepts electrons. This is the likely reason why Gold(III)-bromide occurs only as a dimer of Au2Br6. When heated, gold bromide first forms AuBr and subsequently decomposes into gold and bromine.
