Question

Write any three application of neutralization reaction in our life

Answer 1

1. Tooth decay or cavities

Chocolates and decaying food particles produce acid in our mouth which reacts with enamel i.e. calcium phosphate and leads to cavities. Using toothpaste while brushing help to neutralize the acid since toothpaste is a base.



2. Gastric patients

Anti-acids or antacids are medicines containing bases such as `NaHCO_3 ` (sodium bicarbonate) `Mg(OH)_2` (magnesium hydroxide) neutralize excess of acid in stomach.



3. To treat acidic soils

Plants do not grow well in acidic soils. Bases like `CaO` , `CaCO_3` , ashes of burnt wood are added to the soil to neutralize its acidity.

Similarly basic soils are treated with acids to neutralize its basic nature.
