Soap mixed with water below critical micelle concentration behaves as

Options

A. associated colloids
B. macromolecular colloids
C. normal electrolytic solution
D. multimolecular colloids

Answer

To solve the question regarding the behavior of soap mixed with water below the critical micelle concentration (CMC), we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Critical Micelle Concentration (CMC)**:
- CMC is the concentration of surfactants (like soap) in a bulk phase, above which micelles are formed. Below this concentration, surfactants do not aggregate into micelles.

2. **Behavior of Soap Below CMC**:
- When soap is mixed with water below the CMC, it does not form micelles. Instead, the soap molecules remain dispersed in the solution as individual molecules.

3. **Nature of the Solution**:
- Since the soap molecules are not forming aggregates, the solution behaves like a normal solution. In this case, soap behaves similarly to an electrolyte solution where ions are present but not in the form of aggregates.

4. **Conclusion**:
- Therefore, when soap is mixed with water below the critical micelle concentration, it behaves as a normal electrolytic solution.

5. **Final Answer**:
- The correct answer to the question is that soap mixed with water below critical micelle concentration behaves as a **normal electrolytic solution**.
