प्रश्न
Explain why a finely divided substance is more effective as adsorbent?
टीपा लिहा
उत्तर
- Adsorption is a surface phenomenon and hence, the extent of adsorption depends upon the surface area of the adsorbent.
- Adsorption increases with an increase in the surface area of the adsorbent.
- Finely divided powdered substances provide a larger surface area for a given mass. Hence, a finely divided substance is more effective as an adsorbent.
