Question

Give any two important uses of neutralisation reaction in daily life.

Answer 1

1. Ant bite:

• Whenever bees or red ants bite they inject an acid called formic acid.

• These acids cause burning sensation and pain.

• To suppress the pain, a suitable base in the form of calcium hydroxide (readily available at home) is applied to neutralise the formic acid.

2. Acidity:

• Excessive production of hydrochloric acid in our stomach causes ulcers in the stomach and food pipe.

• In order to neutralize, antacids which are nothing but weak bases like aluminium and magnesium hydroxides are used.
