Question
Chapter 14, Problem 14.117CQ
Interpretation Introduction
Interpretation:
Identify the acid-base pairs. Which side is favoured, accounting for the equilibrium constants.
Concept introduction:
▪ Typically, we must identify which species will accept and donate hydrogen ions.
▪ Species accepting hydrogen ions will be bases
▪ Species donating hydrogen ions will be acids
▪ The equilibrium constants can help to identify which side is favored
To determine which side is favoured

Heparin is used as an anti-coagulant. A risk of heparin use is thrombocytopenia, or low platelet
count. This risk is minimized with the use of low molecular weight heparins (LMWH), therefore it is
desirable to separate LMWH from higher molecular weight heparins. The method of choice to do
this is molecular exclusion chromatography. Below is a chromatogram from a molecular exclusion
chromatographic run. Peaks ranging from A to J are clearly distinguishable. The heparin mixture
that was analyzed had anywhere from 6 to 30 repeat units of monomer (where the heparin with 30
repeat units would be roughly five times the size of the heparin with six repeat units).
a. Which letter most likely represents the peak with 6 repeat units given these heparin polymers
were separated with molecular exclusion chromatography?
b. Explain your reasoning describing the mechanism of retention in molecular exclusion
chromatography.
