Question
Chapter 26.SE, Problem 33AP
Interpretation Introduction
Interpretation:
The pKa1 and pKa2 of proline are 1.99 and 10.60 respectively. Using Henderson-Hasselbalch equation the ratio of protonated and neutral form at pH=2.5 and the ratio of neutral and deprotonated forms at pH=9.70 are to be calculated.
Concept introduction:
Henderson-Hasselbalch equation can be represented as
where [A-] is concentration of the ionized form and [HA] is the concentration of the unionized form at equilibrium.
To calculate:
Using Henderson-Hasselbalch equation the ratio of protonated and neutral form at pH=2.5 and the ratio of neutral and deprotonated forms at pH=9.70 if the pKa1 and pKa2 of proline are 1.99 and 10.60 respectively.
