MCQ
Peptization denotes:
- ADigestion of food.
- BHydrolysis of proteins.
- ✓Breaking and dispersion into colloidal state.
- DPrecipitation of solid from colloidal dispersion.
✓
Answer
Correct option: C.
Breaking and dispersion into colloidal state.
Peptization is a process in which colloidal solution is prepared by adding electrolyte to a precipitate. The electrolyte is added called as peptizing agent. This peptization process also called as deflocculation when the ferric chloride solution is added to the ferric hydroxide precipitate, it gives sol of ferric hydroxide. Therefore, we can say that in peptization, precipitate breaks and disperse into a colloidal solution.
