Options

A. Solid , solid , Lyophobic
B. Liquid , liquid , lyophobic
C. Solid , liquid ,lyophobic
D. Solid ,liquid ,lyophillic

Answer

To solve the question regarding the dispersed phase, dispersion medium, and the nature of the colloidal solution of gold sol, we can break it down into the following steps:

### Step 1: Identify the Dispersed Phase
The dispersed phase in a colloidal solution refers to the phase that is distributed throughout another phase. In the case of gold sol, the dispersed phase is the gold particles themselves.

**Hint:** Look for what is being dispersed in the solution.

### Step 2: Identify the Dispersion Medium
The dispersion medium is the substance in which the dispersed phase is distributed. For gold sol, the dispersion medium is water, as it serves as the liquid in which the gold particles are suspended.

**Hint:** Consider what substance is surrounding or suspending the dispersed particles.

### Step 3: Determine the Nature of the Colloidal Solution
The nature of the colloidal solution can be classified based on the interaction between the dispersed phase and the dispersion medium. Gold sol is considered a lyophobic colloid, meaning that the dispersed phase (gold) does not have a strong affinity for the dispersion medium (water).

**Hint:** Think about how the dispersed phase interacts with the dispersion medium—does it mix well or not?

### Final Answer
1. **Dispersed Phase:** Solid (gold particles)
2. **Dispersion Medium:** Liquid (water)
3. **Nature of Colloidal Solution:** Lyophobic

### Summary
The dispersed phase of gold sol is solid (gold), the dispersion medium is liquid (water), and the nature of the colloidal solution is lyophobic.
