Question

Which of the following pairs of moving phase and stationary phase respectively is correct for column chromatography?

• A. Liquid, Solid
• B. Solid, Liquid
• C. Gas, Liquid
• D. Gas, Solid

Hint:

In adsorption chromatography, the stationary phase is always a solid, while the mobile phase is a liquid.

Answer 1

The Correct Option is A

Step 1: Recall the principle of column chromatography.
Column chromatography separates components based on differential adsorption on a solid stationary phase.
Step 2: Identify the phases used.
The stationary phase is a solid adsorbent such as silica gel or alumina.
The mobile (moving) phase is a liquid solvent or solvent mixture.
Step 3: Conclusion.
The correct pair is Liquid as moving phase and Solid as stationary phase.
