Question
Give at least three differences between the following:
(b) Colloidal Solution and Suspension

Answer

Colloidal SolutionSuspension
1. The particle size is in between 10-7 cm to 10-5 cm.The size of the particles of solute is more than 10-5 cm.
2. The particle are visible under a microscope.The particles of suspension settle down when a suspension is allowed to stand.
3. The particles of a colloidal solution cannot be recovered by evaporation and crystallisation.The particles of suspension can easily be filtered out.
4. The particles of a colloidal solution scatter light.The particles of suspension are visible to the unaided eyitlows
