Question

Compare the properties of suspensions and colloids.

Answer 1

Suspensions	Colloids
1. Suspensions are heterogeneous mixtures.	1. Colloids are heterogeneous mixtures.
2. The particles of suspensions can be seen with naked eyes.	2. The size of particles of a colloid are too small to be individually seen by naked eyes.
3. The particles of a suspension scatter a beam of light passing through it and make its path visible.	3. The particles of colloids are big enough to scatter a of light passing through it which makes its path visible.
4. The solute particles settle down when suspension is kept undisturbed. When the particles settle down it does not scatter light any more.	4. The particles don’t settle down when the colloid left undisturbed, i.e., colloid is quite stable.
5. Suspension is unstable. The components can be separated from the mixture by the process	5. The components cannot be separated from the mixture by the process of filtration or decantation Centrifugation technique is used in separation.
