Why aqua regia don't react with silver?
silver chloride forms, which is insoluble in aqua regia, HCl, or HNO3. silver chloride is soluble in ammonium solutions but this can become very dangerous, as fulminate forms and can detonate when dried, acidifying them with HCl to precipitate the silver and form ammonium chloride solution is a safe way to handle them. insolubility of silver chloride in aqua regia is one reason karat gold is inquatered, and parted in nitric before dissolving gold in aqua regia, the insoluble silver chloride will crust over the gold (from silver in the karat gold), and aqua regia cannot dissolve the gold with an layer of silver chloride protecting the gold from the acids. some small amounts of silver chloride is soluble in aqua regia, remember soluble, or insoluble are relative terms, and can be affected by temperature, PH and so on. metal refiner Richard B.
Why does aqua regia dissolve gold and platinium?
Nitric acid (1 part by volume) mixed with conc.hydrochloric acid (3 parts by volume) produces a mixture called aqua regia. HNO3 + 3HCl → NOCl + 2H2O + 2[Cl] Aqua regia contains nascent chlorine and reacts with noble metals such as gold and platinum to produce chlorides. Pt + 4[Cl] → PtCl4 Au +3[Cl] → AuCl3.
