Colloid:-

•A colloid is a heterogeneous mixture.

•A colloid is quite stable i.e. they do not settle down when left undisturbed.

•Colloids are big enough to scatter a beam of light passing through it and make its path visible. This phenomenon is called Tyndall effect.

•Colloids cannot be separated from the mixture by filtration. But a process called centrifugation, can be used to separated colloids.

•The types of colloids are:-

→Aerosol
