Chapter 9, Problem 4Q

Interpretation Introduction

Interpretation:

The importance to allow the liquid level in the column to drop to the level of alumina before the solution of the compound is separated should be explained.

Concept introduction:

A separation technique used for the segregation of components of chemical mixture based on the difference between the adsorption of different components in stationary and mobile phase is called column chromatography.

It is used for purification or segregation of compounds. It consists of two phases namely:

1. Stationary phase (solid)
2. Mobile phase (generally liquid)

Silica gel is commonly used as the stationary phase.
