Question

what would you expect to happen if a piece of gold was placed in a test tube of hydrochloric acid? why?

Answer 1

Answer:

Muriatic acid, better known today as hydrochloric acid, is a simple, corrosive liquid with well-studied chemical properties. When gold is subjected to treatment with muriatic acid alone, nothing happens. But when \muriatic acid is combined with nitric acid to treat gold, the gold dissolves.
