Question
Write differences between adsorption and absorption.
✓
Answer
| Adsorption | Absorption |
| 1. The concentration of subtances takes place on the interface of two immiscible phases. | 1. The substance is distributed in the whole body of the adsorbent to form a solution of a compound. |
| 2. It is a surface phenome-non. | 2. Absorption equilibrium is slow. |
| 3. In it, the concentration of substance is always greater on the interface than in the bulk. | 3. It is a bulk phenonenon. In if molecules of adsorbate penetrate the whole body of adsorbent. |
