Class 7 Chemistry Acids, Bases and Salts Neutralisation

Neutralisation

The reaction between an acid and a base to give a salt and water is known as a neutralisation reaction. Acids and bases react with each other to nullify the effect of each other. Let us consider a simple reaction. Take a sample of NaOH which is a base and add drops of dilute HCl.

The reaction will be as follows:

Therefore while suffering from acidity it is prescribed to take antacid which are bitter in taste i.e. they are base. And on entering the body the base neutralise the excess acid released into the stomach and convert it into salt and water.
