Can gold be dissolved in sulphuric acid alone? Iodine?
A. Sulfuric acid can dissolve gold, but it is a very dangerous process as the sulfuric acid has to be concentrated and heated to the point sulfur dioxide gas is fumed off, silver or gold will dissolve gold will form a gold persulfate soluble in the very concentrated acid, upon dilution the gold will precipitate out of solution as a powder which can be washed and refined.
