Unit 8.9: Henderson-Hasselbalch Equation
Use the Henderson-Hasselbalch equation to determine the pH of a buffer
solution.
-
Calculate the pH of a buffer made from 0.1 M acetic acid and 0.1 M
sodium acetate.
- If [A−]/[HA] = 2, and pKa = 4.76, what is the pH?
Qualitatively describe how a buffer resists pH changes when acid or base
is added.
- Explain how a buffer reacts when OH− is added.
- Describe the role of the conjugate base in resisting pH change.
