Paper chromatography is also called.............chromatography in which..............constitutes the stationary phase while a....................constitutes the mobile phase.

Answer

**Step-by-Step Solution:**

1. **Identify the Other Name for Paper Chromatography:**
- Paper chromatography is also known as **partition chromatography**. This term reflects the method's principle of separating components based on their different partitioning between two phases.

2. **Define the Stationary Phase:**
- In paper chromatography, the stationary phase is the **water** that is bound to the chromatography paper. The water interacts with the paper and provides a medium for the components to adhere to during the separation process.

3. **Define the Mobile Phase:**
- The mobile phase in paper chromatography consists of a **mixture of solvents**. These solvents move up the paper by capillary action and carry the sample components with them, allowing for separation based on their solubility and interaction with the stationary phase.

**Final Answer:**
Paper chromatography is also called **partition chromatography** in which **water** constitutes the stationary phase while a **mixture of solvents** constitutes the mobile phase.
