Freshly prepared precipitate sometimes gets converted to a colloidal solution by Peptisation.
Option (iv)
Explanation:
- Peptisation is a method in which by addition of a suitable peptising agent precipitate gets altered into a colloidal solution. Precipitate swallows the ions of electrolytes and ultimately breaks into colloidal particles.
- During coagulation, colloidal particles come together to form large size particles and form precipitate. Electrolysis brings chemical decomposition bypassing the electric current through electrolytes.
- Diffusion is a process in which liquid/ gas particles move from the region of Maximum concentration to lower concentration.
