WebApr 30, 2024 · Chloroauric acid is a high-molecular-weight monoprotic acid. The crystalline tetrahydrate contains H 5 O 2+ as well as AuCl 4. It also contains two water molecules. In solid form, chloroauric acid is a hydrophilic (ionic) protic solute. Furthermore, chloroauric acid is water-soluble. Webreaction with hydrochloric acid is an equilibrium reaction which favors formation of chloroaurate anions (AuCl 4-). This results in a removal of gold ions from solution and …
