Question

Explain how charge on colloidal particles develop due to preferential adsorption of ions.

cbse 12 chemistry ​

Answer 1

Answer:

The colloidal particles have a tendency to preferentially adsorb a particular type of ions from the solution. A colloidal particle usually adsorbs those ions which are in excess and are common to its own lattice. This preferential adsorption of a particular type of ions imparts a particular type of charge to colloidal particles.
