For example, zinc metal reacts with hydrochloric acid producing zinc chloride and hydrogen gas. Metals that react with these acids produce a metal salt and hydrogen gas: Generally, non-metals do not react with acids. But which gas is it? Since a chemical reaction between an acid and a metal will produce hydrogen gas, this can be used to determine whether a particular metal has reacted with an acid or not. Sn, Li, Cu ****I've tried all three answers and all have been incorrect. When Acid Mixes Up With a Metal:-Generally, when you combine an acid with a metal, salt gets formed and hydrogen gas gets released.
