Answer:
A) can quickly absorb excess H+ ions to keep a solution from becoming too acidic.
B) can quickly release H+ ions to counteract any increases in the OH- concentration in a solution.
Explanation:
A buffer solution (also, pH buffer) is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. Its pH changes very little when a small amount of strong acid or base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of applications.
