Worksheet: Buffer Capacity
In this worksheet, we will practice calculating the maximum amount of acid/base a buffer can neutralize before pH is significantly affected.
Why does the pH not change significantly when a small amount of an acid or a base is added to a solution that contains equal amounts of the acid and , a salt of its conjugate base?
- A reacts with excess base, while reacts with excess acid.
- BExcess base is removed by reaction with , while excess acid is removed by reaction with .
- C is amphiprotic and reacts with and neutralizes both acids and bases; then converts to , restoring the pH.
