When a base is added to a buffered solution,the buffer will ________.

Question

Quizplus · Accepted Answer

A buffered solution contains both a weak acid and its conjugate base (or a weak base and its conjugate acid). When a base is added to the buffered solution, the buffer will donate H+ ions to neutralize the added base and maintain the pH of the solution. Therefore, choice C (donate H+ ions) is the best choice. Choices A (donate OH- ions) and D (form covalent bonds with the base) are incorrect. Choice B (accept water molecules) is not relevant to the reaction.
