The Correct Option is B
Solution and Explanation
Step 1: Understanding Peptisation
Peptisation is the process of converting a precipitate into a colloidal solution by adding a suitable electrolyte.
Step 2: Explanation
- In peptisation, the electrolyte adsorbs onto the surface of the precipitate, causing it to break into smaller particles that remain suspended in the solution.
- It is widely used in the preparation of colloidal sols.
Thus, the correct answer is Peptisation.
- It is widely used in the preparation of colloidal sols.
Thus, the correct answer is Peptisation.
