उत्तर
The reaction between an acid and a base to form salt and water is called a neutralisation reaction.
\[\ce{Acid + Base -> Salt + Water}\]
When hydrochloric acid reacts with a sodium hydroxide solution, a neutralisation reaction forms sodium chloride and water.
\[\ce{\underset{(Base)}{\underset{Sodium hydroxide}{{NaOH}_{(aq)}}} + \underset{(Acid)}{\underset{Hydrochloric acid}{{HCl}_{(aq)}}} -> \underset{(Salt)}{\underset{Sodium chloride}{{NaCl}_{(aq)}}} + \underset{Water}{H2O_{(l)}}}\]
This is an example of a neutralisation reaction. In this reaction, sodium hydroxide and hydrochloric acid neutralise (nullify) each other to form sodium chloride, which is neutral.
