Colloids

Colloids in chemistry are combinations of two heterogeneous substances in which minute particles of one component are scattered in another substance. The term "dispersion medium" refers to the material in which tiny particles of one substance are suspended. This suspension is referred to as the "dispersed phase" of the other substance. As an illustration, the liquid phase of water is the dispersed phase in the fog, while the dispersion medium is a variety of gases. Colloidal dispersed phase particles are so tiny that we cannot see them with the naked eye. These are the characteristics of colloids: A Tyndall effect can be seen. The light beam is dispersed and its passage through the object is visible. Even after being left alone for some time, they don't calm down. It indicates that colloidal solutions are fairly stable. A filtering procedure is unable to separate them. Centrifugation can be used to separate them. Colloidal particles move in a Brownian manner.
