Freshly prepared precipitate sometimes gets converted to colloidal solution by ……. .

Options

A. coagulation
B. electrolysis
C. diffusion
D. peptisation

Explanation

To solve the question, "Freshly prepared precipitate sometimes gets converted to colloidal solution by …….," we need to identify the process responsible for this conversion.

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Precipitate**: A solid that forms and settles out of a liquid mixture.
- **Colloidal Solution**: A mixture where very small particles are dispersed throughout a substance.

2. **Identifying the Process**:
- The conversion of a freshly prepared precipitate into a colloidal solution occurs through a specific process known as **peptization**.

3. **Defining Peptization**:
- Peptization is the process in which a freshly prepared precipitate is converted into a colloidal solution by the addition of a suitable peptizing agent.

4. **Conclusion**:
- Therefore, the answer to the question is that freshly prepared precipitate sometimes gets converted to colloidal solution by **peptization**.

### Final Answer:
Freshly prepared precipitate sometimes gets converted to colloidal solution by **peptization**.
