Explanation:
Detailed explanation-1: -Base: A solution that has an excess of OH-ions. Another word for base is alkali.
Detailed explanation-2: -Addition of an excess base to a solution of sodium hydroxide means an addition of more hydroxide ions (OH−). This will increase the concentration of hydroxide ions (OH−).
Detailed explanation-3: -The concentration of (OH−) Hydroxide ions increases when the excessive base is added to the solution of Sodium Hydroxide as the base itself dissociates to give out OH− ions which increases their concentration per unit volume.
