Expert Answer
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. |
