Paper chromatography is an example of:

Options

A. adsorption chromatography
B. partition chromatography
C. Thin layer chromatography
D. Column chromatography

Answer

To solve the question regarding what type of chromatography paper chromatography is an example of, we can follow these steps:

### Step 1: Understand the Types of Chromatography
First, we need to understand the different types of chromatography mentioned in the options:
- **Adsorption Chromatography**: This technique involves the adhesion of molecules from a liquid or gas to a solid surface.
- **Partition Chromatography**: This method separates compounds based on their distribution between two phases: a stationary phase and a mobile phase.
- **Thin Layer Chromatography (TLC)**: This is a technique similar to paper chromatography but uses a thin layer of adsorbent on a flat surface.
- **Column Chromatography**: This involves packing a column with a stationary phase and passing a mobile phase through it to separate components.

### Step 2: Analyze Paper Chromatography
Next, we analyze the process of paper chromatography:
- In paper chromatography, a filter paper is used as the stationary phase, which contains layers of cellulose.
- The sample is applied to the paper, and a solvent (the mobile phase) is allowed to move up the paper by capillary action.
- The components of the sample partition between the stationary phase (the paper) and the mobile phase (the solvent).

### Step 3: Identify the Correct Type
Since paper chromatography relies on the partitioning of substances between the stationary phase (the paper) and the mobile phase (the solvent), it is classified as **partition chromatography**.

### Step 4: Conclusion
Based on the analysis, the correct answer to the question is:
**Paper chromatography is an example of Partition Chromatography.**
