What is a neutralisation reaction? Give two examples.
A reaction in which an acid and base react with each other to form salt and water is known as neutralization reaction. During this reaction energy is evolved in the form of heat.
For example:
(i) sodium hydroxide a strong base reacts with strong acid hydrochloric acid produces neutral salt sodium chloride and water molecules.
(ii) In case of indigestion which caused due to the excess production of hydrochloric acid in the stomach resulting in acidity, to neutralise the effect of acid an antacid, Mg(OH)2 which is basic in nature is given, thus gives relief from indigestion.
