WebSo far dilute nitric and 3M HCl aren't doing the job. Sulfuric? Aqua regia? What makes it a pain is I have to justify anything common-but-dangerous for a chem lab. We really don't have the infrastructure to be maintaining a proper lab that has a bucket of piranha for example. So, if I'm ordering sulfuric, it really needs to work. Aqua regia dissolves gold, although neither constituent acid will do so alone. Nitric acid is a powerful oxidizer, which will actually dissolve a virtually undetectable amount of gold, forming gold(III) ions (Au ). The hydrochloric acid provides a ready supply of chloride ions (Cl ), which react with the gold ions to produce tetrachloroaurate(III) anions ([AuCl4] ), also in solution. The reaction wi…
