Question
Chapter 17, Problem 32P
Interpretation Introduction
Interpretation:
The form of carboxylic group of lactic acid at the given pH range for blood plasma should be determined.
Concept Introduction:
For an acid HA; the acid dissociation reaction can be written as.
The acid dissociation constant (Ka) is the ratio of product and reactant for the acid dissociation reaction. Hence it can be written as;.
Henderson-Hasselbalch equation purposed the relation between pH and pKa for weak acids:

The normal pH range for blood plasma is 7.35–7.45. Under these conditions, would you expect the carboxyl group of lactic acid (pKa 3.08) to exist primarily as a carboxyl group or as a carboxylic anion? Explain.
Give at least 5 examples of biological compounds having a carboxylic acid functional group and identify the biochemical importance of each compound.
Using the data in Appendix C, determine which of the following bases is strong enough to deprotonate acetonitrile (CH3CN), so that equilibrium favors the products: (a) NaH; (b) Na2CO3; (c) NaOH; (d) NaNH2; (e) NaHCO3.
