Step 1: Define Differential Adsorption

Differential adsorption means different compounds adsorb on a solid adsorbent surface with different strengths. More polar compounds interact more strongly with a polar adsorbent (like silica gel or alumina), while less polar compounds adsorb weakly.

Step 2: Analyse Each Technique

A. Column Chromatography ✅
- Stationary phase: solid adsorbent (silica gel or alumina) packed in a glass column
- Mobile phase: liquid solvent (eluent)
- Separation mechanism:
