(a)

Interpretation Introduction

Interpretation:

The predominant form of carboxylic acid and an amine at pH 3.0 have to be drawn.

Concept Introduction:

If pKa is greater than the pH value then protonation occurs at that pH.

(b)

Interpretation Introduction

Interpretation:

The component that will be expected to be eluted first has to be identified and explained.

Concept Introduction:

In chromatography elution order depends on the solubility of the compound in stationary phase. Polar compounds are generally insoluble in non-polar stationary phase and hence eluted first. Whereas non-polar compounds are insoluble in polar stationary phase hence eluted first.
