The pK a1 and pK a2 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 pK a1 and pK a2 of proline are 1.99 and 10.60 respectively.
