Asked by George

Which of the following has the greatest buffer capacity? There are three separate problems below.

1. 0.40 M CH3COONa / 0.20 M CH3COOH
2. 0.40 M CH3COONa / 0.60 M CH3COOH
3. 0.30 M CH3COONa / 0.60 M CH3COOH

Thanks!

Take the log[(base)/(acid)]. The one that changes the least has the most buffering capacity. The one that has the best buffering capacity is not listed; that is the one where base = acid. For example,
0.5 M CH3COONa/0.5 M CH3COOH.
