The charge on colloidal particies is due to

Options

  1. Apresence of electrolyte
  2. Bvery small size of particles
  3. Cadsorption of ions from the solution
  4. 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.
