| Liquid ammonia reacts with aurous chloride to form compounds AuCl,3NH3 and AuCl,12NH3; at 18° C. gaseous ammonia and aurous bromide give a white powder, AuBr,2NH3. Liquid ammonia converts aurous iodide into a compound AuI,6NH3, from which ammonia is eliminated by rise of temperature, the substance being completely transformed at 20° C. into AuI,NH3, a compound also formed by the action of ammonia-gas on aurous iodide. |
