(a) Define neutralization reaction with an example.

(b) Give a balanced equation for this reaction.

(c) Give three applications of neutralization reactions.

(a) The reaction between an acid and a base that forms salt and water only is referred to as Neutralization reaction.

Reaction between an acid and an alkali to form salt and water only is an example of neutralization reaction.

(b) NH₄OH + HCl ⟶ NH₄Cl + H₂O

(c) Applications of neutralization reactions are as follows :

1. When someone is stung by a bee, formic acid enters the skin and causes pain, which can be relieved by rubbing the spot with slaked lime or baking soda, both of which are bases and thus neutralize the acid.
2. The acid which is accidentally spilt on to our clothes can be neutralised with ammonia solution.
3. If soil is somewhat acidic and thus unfavourable for the growth of certain crops, slaked lime is added to neutralise the excess acid.
