The metal/s that will react with hydrochloric acid needs to be identified. Concept introduction: All the transition metals have the tendency to react spontaneously with H+ ions present in a strong acid such as HCl, HBr and H 2 SO 4 . A metal which has a positive oxidation potential can be oxidized by the H+ ions present in the acid. The products so formed are a cation of that transition metal and hydrogen gas is evolved during this reaction.
