The charge on colloidal particies is due to

Options

Apresence of electrolyte
Bvery small size of particles
Cadsorption of ions from the solution
Dcan't be determined

Correct answer

C. adsorption of ions from the solution

Step-by-step solution

The colloidal particles have a tendency to preferentially adsorb a particular type of ions form the solution. This preferential adsorption of a particular type of ions imparts a particular type of charge to colloidal narticles.
