What do buffers consist of?
A) equal molar amounts of a weak acid and a salt of the weak acid
B) equal amounts of a strong acid and a salt of the strong acid
C) equal molar amounts of a strong base and a salt of the strong base
D) equal amounts of a strong acid and a strong base

Question

Quizplus · Accepted Answer

Buffers consist of a weak acid and its conjugate base or a weak base and its conjugate acid, in equal molar amounts, to resist changes in pH. Option A describes a common type of buffer system. Option B is not a buffer because a strong acid and its salt will produce an acidic solution. Option C is not a common type of buffer system. Option D is not a buffer because a strong acid and a strong base will neutralize each other, resulting in a pH of 7.
