Solution
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 excess acid produced in the stomach.
Mg(OH)2+2HCl⟶MgCl2+2H2O
