Aurous bromide, AuBr






When auric bromide is heated, bromine is evolved, and aurous bromide left as a green mass. It is also formed by heating auribromic acid, HAuBr4, the auric bromide formed decomposing at 115° C. Above this temperature it is decomposed into gold and bromine, and reacts with water like aurous chloride. Aqueous hydro- bromic acid converts it into gold and auribromic acid, HAuBr4:

3AuBr=AuBr3+2Au;
AuBr3+HBr=HAuBr4.

It dissolves in solutions of alkali-metal bromides.
