Why isn't hydrochloric acid used to both dissolve and precipitate silver?
2 answers
The solubility of silver chloride in water is quite low and it is even lower in HCl. So when you put a piece of silver in HCl it forms a coating of silver chloride which prevents further dissolving of the silver. However, with HNO3 the silver nitrate that is formed is soluble so the silver will dissolve.
