Question

properties of calloids

Answer 1

Properties of colloids:-

• 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 through it and make its path visible.

• They do not settle down when left undisturbed, i. e. 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.
