Question
Chapter 22, Problem 32P
Interpretation Introduction
Interpretation:
The structure of the conjugate acid of carnosine is to be drawn.
Concept introduction:
An acidic substance in a reaction donates a proton, whereas base in a reaction accepts a proton. The elimination of a proton leads to the formation of a conjugate base. When the base accepts a proton, the species formed is known as conjugate acid.

What is the pKa of the conjugate acid of the reaction?
The pKa values of the carboxylic acid groups of oxaloacetic acid are 2.22 and 3.98.
a. Which carboxyl group is the stronger acid? b. The amount of hydrate present in an aqueous solution of oxaloacetic acid depends on the pH of the solution: 95% at pH 0, 81% at pH 1.3, 35% at pH 3.1, 13% at pH 4.7, 6% at pH 6.7, and 6% at pH 12.7. Explain this pH dependence.
