Question

In column chromatography, the stationary phase is:

RankGuru · Accepted Answer

**Column Chromatography** is based on the principle of differential adsorption.
- **Stationary Phase**: A porous material with a large surface area, known as an **Adsorbent**, is packed into a vertical column. Common materials include **Silica gel** ($SiO_2$) and **Alumina** ($Al_2O_3$).
- **Mobile Phase**: An appropriate solvent (or mixture) flows down through the adsorbent.
- **Separation**: Different components of the mixture adsorb onto the stationary phase with varying strengths. The less strongly adsorbed components move faster and are eluted first.
