Solution
Correct Answer:
Partition
Paper Chromatography is a specific type of Partition Chromatography.
- Stationary Phase: Water molecules trapped or adsorbed between the cellulose fibers of the chromatography paper.
- Mobile Phase: An organic solvent that moves up the paper by capillary action.
- Separation: The components of the mixture distribute (partition) themselves between the stationary water phase and the mobile organic phase based on their relative solubilities. Each component moves at a different rate depending on its partition coefficient.
This easy difficulty chemistry question is from the chapter purification and characterisation of organic compounds, covering the topic of paper chromatography. It appeared in the 2025 exam.
