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⟶MgCl 2 +2H 2O
