Is gold III bromide soluble?
Gold(III) Bromide (AuBr3), also known as Digold Hexabromide (commonly existing in nature as a dimer with the molecular formula Au2Br6) is a highly water soluble crystalline Gold source for uses compatible with Bromides and lower (acidic) pH.
Does bromine react with gold?

Is gold III bromide ionic or covalent?
Formula and structure: Gold bromide chemical formula is AuBr3 and its molecular weight is 436.69 g mol–1. The molecule is formed by a gold cation Au3+ and 3 bromide anion Br –, that are bounded by ionic bonds. The gold (III) bromide structure is mostly found as a dimer of digold hexabromide.
How are cations named?
The cation is named first. If the cation is a “simple” cation (“simple” ion is made from only one element.) the cations is named after the element. If the cation is a polyatomic cation (a polyatomic ion is made from two or more covalently bonded elements.)
