उत्तर
Coagulation and Peptization
| Coagulation | Peptization |
| The process of settling of colloidal particles is called coagulation or precipitation of the sol | The process of converting a precipitate into colloidal sol by shaking it with dispersion medium in presence of small amount of electrolyte (peptising agent) are also known as associated peptization |
