Chapter 25, Problem 25.41P

Interpretation Introduction

Interpretation:

The dominant species of each compound at each $\text{pH}$ has to be drawn and the behaviour of the retention factor have to be explained.

Concept Introduction:

Retention factor:

The time that is necessary to elute that peak minus the minimum possible time for the travel of unretained solute through the column is called as retention factor. The retention factor is calculated using the equation,

$\text{k=}\frac{{\text{t}}_{\text{r}}{\text{-t}}_{\text{m}}}{{\text{t}}_{\text{m}}}$

Where,

${\text{t}}_{\text{r}}$ = retention time

${\text{t}}_{\text{m}}$ = minimum possible time for the travel of unretained solute through the column.
