Question

List two differences and two similarities between colloids and suspension.

Answer 1

Differences:

Colloidal particles are smaller than suspension particles.

Colloid particles do not aggregate or separate upon standing. On the other hand a suspension, over time, will separate into layers because of the difference between density and solubility.

Similarities:

The path of light is visible through a colloid as well as a suspension when the suspended particles are suspended.
