Question

Describe any three properties of a colloidal solution

Answer 1

A colloid is a heterogeneous mixture.

� The size of particles of a colloid is too small to be individually seen by naked eyes.

� Colloids are big enough to scatter a beam of light passing through it and make its path visible.

� They do not settle down when left undisturbed, that is, a colloid is quite stable.

� They cannot be separated from the mixture by the process of filtration. But, a special technique of separation known as centrifugation can be used to separate the colloidal particles.
