Chromatography is a technique based on………………….. Adsorption of defferent constituents of mixture.

Answer

**Step-by-Step Solution:**

1. **Understanding Chromatography**: Chromatography is a separation technique used to separate different components of a mixture. It relies on the differential affinities of the components for a stationary phase and a mobile phase.

2. **Principle of Separation**: The technique is based on the principle of adsorption. In chromatography, different substances in a mixture adhere to the stationary phase to varying degrees, leading to their separation as they move through the mobile phase.

3. **Physical Adsorption**: The separation occurs due to physical adsorption, where the components of the mixture interact with the stationary phase (like filter paper or silica gel) based on their unique properties, such as polarity and size.

4. **Application Example**: For instance, when a drop of ink is placed on filter paper, the different colored pigments in the ink will travel at different rates, leading to the separation of colors. This happens because each pigment has a different adsorption capacity on the filter paper.

5. **Conclusion**: Therefore, chromatography is a technique based on the adsorption of different constituents of a mixture, specifically focusing on their physical adsorption characteristics.

**Final Answer**: Chromatography is a technique based on the adsorption of different constituents of a mixture.
