Which one of the following does not involve coagulation?
- A Formation of delta regions
- B Peptization
- C Treatment of drinking water by potash alum
- D Clotting of blood by the use of ferric chloride
Answer & Solution
Correct Answer
(B) Peptization
Step-by-step Solution
Detailed explanation
Coagulation is the phenomenon of conversion of colloidal sol into precipitate while in peptization, a fresh precipitate is converted into sol by adding electrolyte. Hence, it is clear that peptization does not involve coagulation.
