There are certain substances which behave as normal, strong electrolyte at low concentration but at higher concentration they behave as colloidal solutions due to the formation of aggeregated particles. Such colloidals called associated colloids and the aggeregated particles are called micelles. The formation of micelles take place above certain concentration called critical micelization concentration called critical micellization concentration (CMC) and a characteristic temperature.
Micelles are

Options

A. Emulsion-cum-gel
B. Adsorbed catalyst
C. Associated colloids
D. Ideal solutions

Answer

To solve the question regarding micelles and their classification, we can break down the information provided in the question and the video transcript step by step.

### Step-by-Step Solution:

1. **Understanding Micelles**:
- Micelles are formed when certain substances, which act as strong electrolytes at low concentrations, aggregate to form larger particles when the concentration increases. This aggregation leads to the formation of colloidal solutions.

2. **Definition of Associated Colloids**:
- The substances that exhibit this behavior are known as associated colloids. They behave like normal electrolytes at lower concentrations but transition to colloidal behavior at higher concentrations.

3. **Critical Micellization Concentration (CMC)**:
- The concentration at which micelles begin to form is called the Critical Micellization Concentration (CMC). This is a specific threshold concentration that indicates the onset of micelle formation.

4. **Characteristics of Micelles**:
- Micelles are characterized by their ability to encapsulate hydrophobic substances in their core while maintaining a hydrophilic exterior, allowing them to exist in an aqueous environment.

5. **Identifying the Correct Option**:
- The question asks to classify micelles among the given options: emulsion cum gel, adsorbed catalyst, associated colloids, or ideal solution.
- Based on the definition and characteristics discussed, micelles fall under the category of associated colloids.

6. **Conclusion**:
- Therefore, the correct answer is that micelles are associated colloids.

### Final Answer:
Micelles are associated colloids.
