Acids and Bases React with Metals

Acids react with most metals to form a salt and hydrogen gas. As discussed previously, metals that are more active than acids can undergo a single displacement reaction. For example, zinc metal reacts with hydrochloric acid producing zinc chloride and hydrogen gas.

FOR EXAMPLE:

For example, zinc metal reacts with hydrochloric acid producing zinc chloride and hydrogen gas. Bases also react with certain metals like zinc or aluminum for example to produce hydrogen gas. For exanple, sodium hydroxide reacts with zinc and water to form sodium zincate and hydrogen gas

$\Huge\bf\pink{Answer\::}$

When acids and some bases reacts with metal, H2 gas is evolved.
