Which of the following items would you use to make an acidic buffer solution?
A)acetic acid (a weak acid)and hydrochloric acid (a strong acid)
B)hydrochloric acid (a strong acid)and sodium chloride
C)acetic acid (a weak acid)and sodium acetate
D)hydrochloric acid (a strong acid)and sodium hydroxide (a strong base)
E)ammonium hydroxide (a weak base)and ammonium chloride

Question

Quizplus · Accepted Answer

A buffer solution requires a weak acid and its conjugate base (or a weak base and its conjugate acid) to effectively resist changes in pH. Acetic acid is a weak acid and sodium acetate is its conjugate base, making them a good choice for an acidic buffer solution. Option A contains a strong acid and a weak acid, which will not form a buffer. Option B contains a strong acid and its salt, which can form a buffer but it will be a acidic buffer. Option D contains a strong acid and strong base, which will not form a buffer. Option E contains a weak base and its salt, which can form a basic buffer but not an acidic buffer.
