Class 10 Chemistry Acids Bases Salts Reaction of metals with acids

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.


  • For instance, Magnesium reacts with dilute hydrochloric acid to form magnesium chloride and hydrogen.

  • Electrochemical series is the development of a series of metals that are arranged as per their reactivity in a sequence from highest to lowest. Copper does not react with hydrochloric acid because it is below hydrogen in the electrochemical series due to which it does not react liberate hydrogen but reacts with sulphuric acid.
