The process used in separating large particles from smaller ones in a solution is called

Options

A. Chromatorgraphy
B. Dialysis
C. Osmosis
D. Tyndallisation

Answer

To solve the question "The process used in separating large particles from smaller ones in a solution is called," we need to analyze the options provided and determine which one correctly describes the process of separation based on particle size.

### Step-by-Step Solution:

1. **Understanding the Question**: The question is asking for a specific process that separates large particles from smaller ones in a solution.

2. **Analyzing the Options**:
- **Chromatography**: This is a laboratory technique used for separating mixtures, but it does not specifically focus on separating large particles from small ones. Therefore, this option is incorrect.

- **Dialysis**: This process involves the movement of small particles (like nitrogenous waste) through a semi-permeable membrane while larger particles (like proteins) are retained. This means that dialysis effectively separates large particles from smaller ones, making this option the correct answer.

- **Osmosis**: This is the movement of solvent molecules through a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. It does not specifically separate particles based on size, so this option is incorrect.

- **Tyndallization**: This is a method of sterilization that involves the removal of living organisms and their spores from an object. It does not pertain to the separation of particles in a solution, making this option incorrect.

3. **Conclusion**: After evaluating all the options, the correct answer to the question is **Dialysis**, as it specifically addresses the separation of large particles from smaller ones in a solution.

### Final Answer:
The process used in separating large particles from smaller ones in a solution is called **Dialysis**.
