Chapter 23, Problem 23.9P

Interpretation Introduction

Interpretation:

Reason behind the separation of three acids and the order of elution has to be explained.

Concept Introduction:

If ${\text{pK}}_{\text{a}}$ of species is less than that of $\text{pH}$ of solution then species will release its acidic proton and hence ionized. Greater the average charge of the compound, more it is excluded from the ion exchange resin, and more rapidly it is eluted
