Question

What is a neutralisation reaction? Give two examples.​

Answer 1

During indigestion (caused due to the production of excess of hydrochloric acid in the stomach), we administer an antacid (generally milk of magnesia,Mg(OH)2, which is basic in nature). The antacid neutralizes the excess of acids and thus gives relief from indigestion.

Answer 2

Answer:

A neutralization reaction is when an acid and a base react to form water and salt and involves the combination of hydrogen ions and hydroxyl ions to generate water. The neutralization of a strong acid and strong base has a pH equal to 7.

Example – 1: When Sodium hydroxide is added to hydrochloric acid. Sodium chloride and water are formed.

NaOH+HCl⟶NaCl+H2O

Example - 2: Milk of magnesia, which is a base, is given as antacid in the case of indigestion, to neutralize the more acid produced in the stomach.

Mg(OH)2 +2HCl⟶MgCl2 +2H2O
