Sulphur sol is

Options

A. Macromolecular colloid
B. Multi molecular colloid
C. Associated colloid
D. Micelle

Answer

**Step-by-Step Text Solution:**

1. **Understanding Sulphur Sol:**
- Sulphur sol is a colloidal solution where sulfur particles are dispersed in a medium. The particles in this sol are not single molecules but clusters of molecules.

2. **Composition of Sulphur Sol:**
- The particles in sulphur sol are composed of approximately 1000 molecules of sulfur. This indicates that the particles are not simple monomolecular entities but rather consist of multiple molecules.

3. **Classification of Colloids:**
- Colloids can be classified based on the size and nature of their dispersed phase. In this case, since the particles are composed of many molecules, sulphur sol is classified as a multimolecular colloid.

4. **Defining Multimolecular Colloids:**
- Multimolecular colloids are those where the dispersed phase consists of aggregates of many molecules (in this case, sulfur). This contrasts with macromolecular colloids, which consist of large single molecules.

5. **Conclusion:**
- Based on the characteristics of sulphur sol, it is correctly classified as a multimolecular colloid.

**Final Answer:**
- Sulphur sol is a multimolecular colloid.
