Question

In adsorption chromatography mobile phase will be:

• A. only solid
• B. only liquid
• C. only gas
• D. liquid as well as gas

Answer 1

The correct option is D liquid as well as gas

In adsorption chromatography, mobile phase will be liquid as well as gas because the mobility of liquid and gases is more as compared to solids and they can interact and pass through solid stationary phase easily. The stationary phase will be solid.
In column chromatography, mobile phase is solvent and stationary phase is silica gel.
In gas chromatography mobile phase is carrier gas.
