Gold is an almost nonreactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore.
A superior, dry, nonhazardous substitute for nitric acid when making aqua regia. This very dense chemical mixture dissolves instantly, making it far more economical to use than sodium nitrate. MX3 possesses all of the advantages that sodium nitrate has over nitric acid, including: It is far less hazardous; Fumes are reduced by 9095%
tip=sodium nitrate is hard to desolve in liquids other than water. with that said the mixing goes alot faster if you add 1 cup distilled water for each cup of sn to predesolve it. once the silver is desolved wait 30 minutes then pour off the liquid into a clean container. let it cool if heat was used.
