Question:
Which of the following statement is correct for paper chromatography?
Which of the following statement is correct for paper chromatography?
Show Hint
In paper chromatography, the stationary phase is water trapped in paper, while the mobile phase is the liquid solvent.
Updated On: Jan 16, 2025
- Paper sheet forms the stationary phase.
- Water present in the pores of the paper forms the stationary phase.
- Paper and water present in its pores together form the stationary phase.
- Water present in the mobile phase gets absorbed by the paper which then forms the stationary phase.

The Correct Option is B
Solution and Explanation
Paper Chromatography: Key Concepts
Phases Involved:
- Stationary Phase: Water trapped in the pores of the chromatography paper acts as the stationary phase.
- Mobile Phase: A liquid solvent serves as the mobile phase, which travels through the paper carrying the solute components.
Mechanism of Separation:
- Solute components separate based on their differential affinity towards the stationary phase (water) and the mobile phase (solvent).
- Compounds with higher affinity for water (stationary phase) move more slowly.
- Compounds with higher solubility in the solvent (mobile phase) move faster.
Applications:
- Used for separating mixtures of pigments, amino acids, or other small molecules.
- Effective for identifying and analyzing components in complex mixtures.
