Colloidal dispersions show numerous properties; one of these is the scattering of a light beam directed by the dispersion of the colloid, it is called as the Tyndall effect and its extent is because of the number and size of particles present. At the point when seen under ambient light it seems translucent, overcast contingent upon the kind of colloid and the concentration of dispersion and degree of the particle. It is called as a Brownian movement because of the bombardment of colloidal particles of the medium of dispersion. If the particle size is less than the 5G it observed by the Brownian movement.
The presence of a charge on the particles of colloidal provides them electrical properties. At the point when exposed to an electrical potential, it can be compelled to move in the direction of the electrode of inverse charge. This is recognized as electrophoresis and can be utilized to separate a blend of colloidal substances, for example, proteins.
