A) Why does a buffer solution require a weak acid/base conjugate pair, as opposed to a strong acid, and its conjugate? A strong acid will completely dissociate, suggesting that the conjugate base is really weak and will not neutralize any additional H+ ions. A strong acid will completely dissociate, suggesting that the conjugate base is really strong and will not neutralize any additional H+ ions. A strong acid will only partially dissociate, suggesting that the conjugate base is really weak...
