Question

In paper chromatography:

• A. Mobile phase is liquid and stationary phase is solid.
• B. Mobile phase is solid and stationary phase is liquid.
• C. Both phases are liquids.
• D. Both phases are solids.

Hint:

In paper chromatography, a liquid mobile phase moves through a solid stationary phase.

Answer 1

The Correct Option is C

Step 1: Paper chromatography.
In paper chromatography, the mobile phase is usually a liquid, and the stationary phase is typically a solid (the paper itself). However, in some cases, both phases can be liquids, especially in more advanced techniques.
Thus, the correct answer is (3).
