Options

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

Answer

To solve the question regarding the disperse phase, dispersion medium, and the nature of the colloidal solution of gold sol, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Disperse Phase**:
- The disperse phase in a colloidal solution refers to the substance that is dispersed in another substance. In the case of gold sol, the gold particles are the ones that are dispersed.
- Therefore, the disperse phase of gold sol is **solid** (gold particles).

2. **Identify the Dispersion Medium**:
- The dispersion medium is the substance in which the disperse phase is distributed. For gold sol, the gold particles are dispersed in a liquid medium.
- Thus, the dispersion medium of gold sol is **liquid**.

3. **Determine the Nature of the Colloidal Solution**:
- The nature of the colloidal solution can be classified as either lyophilic (solvent-attracting) or lyophobic (solvent-repelling). Gold, being a metal, does not easily form a colloid when mixed with solvents, indicating that it is not attracted to the solvent.
- Therefore, the nature of the colloidal solution of gold sol is **lyophobic**.

4. **Compile the Results**:
- From the above analysis, we conclude:
- Disperse Phase: **Solid**
- Dispersion Medium: **Liquid**
- Nature of Colloidal Solution: **Lyophobic**

5. **Final Answer**:
- The disperse phase, dispersion medium, and the nature of colloidal solution of gold sol respectively are **solid, liquid, lyophobic**.
