MCQ
The peptizing agent used in Peptization is a/ an:
- AStabilizer.
- ✓Electrolyte.
- CProton donor.
- DPromoter.
✓
Answer
Correct option: B.
Electrolyte.
Peptization is the process responsible for the formation of stable dispersion of colloidal particles in dispersion medium. In other words it may be defined as a process of converting a precipitate into colloidal sol by shaking it with dispersion medium in the presence of small amount of electrolyte. The electrolyte used in this process is called as peptizing agent.
