Question

What is peptization and coagulation?

Answer 1

Peptization

• Peptization can be defined as the process of converting a precipitate into colloidal sol by shaking it with the dispersion medium in the presence of the small amount of electrolyte.
• Peptization is also called deflocculation.
• This process is majorly used for colloids or for precipitation reactions in the aqueous medium.

Coagulation

• The process of settling of colloidal particles is called as coagulation of precipitation of the sol.
• The major coagulation methods are electrophoresis, by mixing two opposite sols, boiling, and dialysis.
