The techinque of separation of the components of a mixture in the solution based on their differential adsorption is called ……….

Explanation

**Step-by-Step Solution:**

1. **Understanding the Concept**: The question asks about a technique used for separating components of a mixture based on their differential adsorption. This means that different components of the mixture will adhere to a surface (the stationary phase) to different extents.

2. **Identifying the Technique**: The technique that fits this description is known as **chromatography**. Chromatography is widely used in chemistry for separating and analyzing compounds in a mixture.

3. **Phases in Chromatography**: In chromatography, there are two main phases:
- **Mobile Phase**: This is the phase that moves through the stationary phase. It can be a liquid or gas and carries the components of the mixture.
