Answer

Reaction of metals with acids: -

Metals react with acids and displaces hydrogen from the acids to produce hydrogen gas and metal salt. If a matchstick is brought near the mouth of the tube containing the product of the reaction then we hear a pop sound. It is this hydrogen gas that burns with a pop sound.

Answer

Reactions of acids with metals

Acids react with most metals and, when they do, a salt is produced. But unlike the reaction between acids and bases, we do not get water. Instead we get hydrogen gas.

This is the general word equation for the reaction:

metal + acid → salt + hydrogen

For example : -

magnesium reacts with hydrochloric acid to produce magnesium chloride:

magnesium + hydrochloric acid → magnesium chloride + hydrogen
