Which Buffer System Is the Best Choice?

The hypochlorous acid buffer pair (HClO/KClO

) is the best choice as it has a pKa = 7.53.

Which of the following buffer systems is the best choice to create a buffer with pH 7.20 explain your rationale?

The buffer with a pKa closest to 7.20 would be the best choice because it has the least adjusting to do in the base/acid ratio in order to reach a buffer of pH = 7.20.

What is the most effective buffer system?

A buffer is most effective when the amounts of acid and conjugate base are approximately equal. As a general rule of thumb, the relative amounts of acid and base should not differ by more than tenfold.
