Distinguish between a dilute acid and a weak acid.
Original Khojo Papers practice question — not from a past board paper.
Answer
Dilute refers to the amount of water present with a given amount of acid, that is the concentration. Weak refers to how far the acid ionises in water. A solution can be a dilute solution of a strong acid, or a concentrated solution of a weak acid.
