which of the following is an example of assiciated colloid ?

Options

A. protein in water
B. Soap in water
C. Rubber in benzene
D. `FeCl_(3) " in " H_(2)O`

Answer

To determine which of the following is an example of an associated colloid, we need to understand the concept of associated colloids.

### Step-by-Step Solution:

1. **Definition of Associated Colloids**:
- Associated colloids are systems where the dispersed phase consists of aggregates of molecules or ions. These aggregates form due to the association of individual particles in the dispersion medium.

2. **Characteristics of Associated Colloids**:
- They typically occur in micro-hydrous systems.
- The particles in the dispersed phase are formed by the agglomeration of smaller particles or molecules.

3. **Examples of Associated Colloids**:
- A common example of an associated colloid is soap in water. When soap is added to water, it forms micelles, which are aggregates of soap molecules. This is a classic case of associated colloids.

4. **Conclusion**:
- Based on the definition and characteristics, the correct answer would be the option that represents soap in water, as it exemplifies the concept of associated colloids.

### Final Answer:
- The example of an associated colloid is **soap in water**.
