The colloidal system in which the disperse phase and dispersion medium are both liquids is known as ?

Answer

To solve the question regarding the colloidal system where both the disperse phase and the dispersion medium are liquids, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Colloidal Systems**:
- A colloidal system consists of two phases: the disperse phase (the particles that are dispersed) and the dispersion medium (the substance in which the disperse phase is distributed).

2. **Identifying Phases in the Question**:
- In this case, we are looking for a colloidal system where both the disperse phase and the dispersion medium are liquids.

3. **Defining Emulsions**:
- The colloidal system that fits this description is known as an **emulsion**. An emulsion is a mixture of two immiscible liquids where one liquid (the disperse phase) is dispersed in the other (the dispersion medium).

4. **Characteristics of Emulsions**:
- In emulsions, the dispersed droplets (which are the disperse phase) are larger than the dispersion medium. This is a key feature that distinguishes emulsions from other types of colloidal systems.

5. **Examples of Emulsions**:
- A common example of an emulsion is the mixture of oil and water. In this case, oil acts as the disperse phase, while water serves as the dispersion medium.

6. **Conclusion**:
- Therefore, the answer to the question is that the colloidal system in which both the disperse phase and the dispersion medium are liquids is called an **emulsion**.

### Final Answer:
The colloidal system in which the disperse phase and dispersion medium are both liquids is known as an **emulsion**.
