उत्तर
(a) The reaction between an acid and a base to form salt and water only is referred to as a neutralisation reaction.
(b) NaOH + HCl → NaCl + H2O
(c) Applications of neutralisation reactions:
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.
Acid which is accidentally spilled on to our clothes can be neutralised with ammonia solution.
If soil is somewhat acidic and thus unfavourable for growing of certain crops, slaked lime is added to neutralise the excess acid.
