Colloid is a heterogeneous mixture. Thr size of particles of a colloid is too small to be individually seen by naked eyes. They don't settle down when left undisturbed, that is, a colloid is quite stable. Colloid are big enough to scatter a beam of light passing through it and make its path visible.
