Concept explainers
(a)
Interpretation: The equilibrium constant for the given reaction if Ka for the carboxylic group of glycine is
Concept Introduction: Amino acids are the organic compounds which have two functional groups; amino group and carboxylic acid.
The carboxylic acid group is acidic in nature and the acid dissociation constant can be written as Ka whereas amino group is basic in nature as it can accept H+ ion to form −NH3+ ion. The base dissociation constant can be written as Kb.
(a)
Answer to Problem 152AE
Explanation of Solution
Given:
Ka for the carboxylic group of glycine =
Kb for amino group =
The base dissociation of glycine can be written as:
This reaction is reverse of the equation (a). Thus the equilibrium constant for the reaction (a) can be written as:
(b)
Interpretation: The equilibrium constant for the given reaction if Ka for the carboxylic group of glycine is
