The liquid-liquid colloidal dispersions are called……………..

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term used to describe liquid-liquid colloidal dispersions.

2. **Identifying the Type of Dispersion**: In colloidal chemistry, dispersions can be classified based on the states of the dispersed phase and the dispersion medium. Here, both the dispersed phase and the dispersion medium are liquids.

3. **Defining the Term**: The term used for a colloidal dispersion where both the dispersed phase and the dispersion medium are liquids is called an "emulsion."

4. **Examples of Emulsions**: Common examples of emulsions include mixtures of oil and water, where one liquid (oil) is dispersed in another liquid (water). A typical example is "oil in water" (O/W) emulsion.

5. **Final Answer**: Therefore, the answer to the question is that liquid-liquid colloidal dispersions are called "emulsions."
