Differentiate between peptisation and coagulation
Peptisation and Coagulation
| Peptisation | Coagulation |
|---|---|
| It is the formation of stable colloids in a dispersion medium. | It is the gelling or clumping of the particle. |
| Electrolyte is added whose one ion in common with one ion of precipitate. | Coagulation is carried out by an electrolyte whose one ion is oppositely charged to one ion of the sol. |
| The particles of precipitate absorb common ion of the electrolyte. | The particles of the sol take up the ions which are oppositely charged and get neutarlised. |
| Example: Peptisation of silver iodide using KI solution. | Example: Particles in milk can get coagulated to form yogurt. |
