What Happens When Metals React with Acids?

Answer

When a metal reacts with an acid a chemical reaction takes place and the hydrogen ion in the acid is displaced by the reactive metal ion to form either a salt or an oxide. Hydrogen gas is also formed. Effervescence can be observed in some cases.

When a metal reacts with an acid, a metal salt and hydrogen gas are produced as the only products. However, this general rule does not apply to concentrated nitric acid where nitrogen II gas is evolved. Besides that, the overall reactions usually depend on the type of acid being used.
Metal which is an element that conducts heat and electricity will produce salt and hydrogen when it reacts with acid which is a substance that can be identified as tasting sour and reacts with many substances. However, it is important to note that not all acids will react with metals.
