Question

characteristics of suspension and colloids

Answer 1

Characteristics of suspension
1. Its a heterogeneous mixture.
2. Particles of a suspension can be seen by the naked eye.
3. Particles of a suspension scatter a beam of light passing through it and makes its path visible.
4. The solute particles settle down when a suspension is left undisturbed, that is, a suspension is unstable. They can be separated from mixture by filtration.




Characteristics of colloidal solutions
1. It is a heterogeneous mixture.
2. Size of particles of a colloid are too small to be individually seen by naked eyes.
3. Colloids are big enough to scatter a beam of light passing through it and makes its path visible.
4. They don't settle down when undisturbed, that is, a colloid is quite stable.
5. They cannot be separated from mixture by the process of filtration. But, a special technique of separation known as centrifugation can be used to separate colloidal particles.

Answer 2

•It is a heterogeneous mixture.

•Particles of solute do not dissolve in solvent rather they remained suspended in a bulk throughout.

•The size of particle of suspension is large enough to be visible from naked eyes.

•Particles of suspension scatter a large beam of light passing through it.

•They cannot be separated from mixture by filtration process but separated by centrifugation.
