The phenomenon of converting colloidal solution into suspension is known as…………………

Answer

To answer the question regarding the phenomenon of converting a colloidal solution into a suspension, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Colloidal Solutions**:
- A colloidal solution consists of particles that are typically between 1 nanometer and 1000 nanometers in size. These particles are dispersed throughout the medium and exhibit Brownian motion, meaning they are in constant motion.

2. **Understanding Suspensions**:
- A suspension contains larger particles, usually greater than 1000 nanometers. In a suspension, these particles do not remain suspended indefinitely; they tend to settle at the bottom of the container over time.

3. **The Process of Conversion**:
- The conversion of a colloidal solution into a suspension can occur through a process where the stability of the colloidal particles is disrupted. This can be achieved by adding an electrolyte to the colloidal solution.

4. **Role of Electrolytes**:
- When an electrolyte is added, it neutralizes the charge on the colloidal particles, leading to their aggregation. This aggregation causes the particles to clump together and eventually settle out of the solution, forming a suspension.

5. **Terminology**:
- The process of converting a colloidal solution into a suspension through the addition of an electrolyte is known as **coagulation** or **flocculation**.

### Final Answer:
The phenomenon of converting a colloidal solution into suspension is known as **coagulation** or **flocculation**.
