PG321-Quiz on Lecture 2

A physical method of separation in which the components to be separated are distributed between two immiscible liquids

• Partition

• Extraction

• Chromatography

• Distribution

According to the mechanism involved in differential migration of the solutes, chromatographic techniques are classified into planar and columnar.

• True

• False

Removal of adsorbed solutes from stationary phase using eluent is known as

• Eluate

• Effluent

• Elution

• Retention volume

It is a type of mobile phase that has more affinity to the adsorbent than the solvent but less than the solutes (it allows the solutes to move)

• Solvent

• Developer

• Eluent

• Displacer

A stationary phase Not used for separation of phenolics or carboxylic acids

• Silica gel

• Charcool

• Alumina

• Kiselguhr
