Peptisation is :

Options

A. Conversion of a colloidal into precipitate form
B. Conversion of precipitate into colloidal sol
C. Conversion of metal into colloidal sol by passage of electric current
D. Conversion of colloidal sol into macromolecules

Explanation

**Step-by-Step Solution:**

1. **Understanding Peptization:**
Peptization is a process in which a precipitate (PPT) is converted into a colloidal solution (colloidal sol). The particle size of the colloidal sol ranges from 1 to 100 nanometers.

2. **Role of Electrolytes:**
The conversion of the precipitate into a colloidal sol is achieved by adding an electrolyte. The electrolyte dissociates into ions when dissolved in water.
