-
Coagulation
-
Electrophoresis
-
Electroosmosis
-
Tyndall effect
D.
Tyndall effect
Coagulation is generally brought about by the addition of electrolytes. When an electrolyte is added to a colloidal solution, the particles of the sol take up the ions which are oppositely charged. As a result, their charge gets neutralised.
Electrophoresis: The movement of colloidal particles under an applied electric potential is called electrophoresis. Electroosmosis may be defined as a phenomenon in which the molecules of the dispersion medium are allowed to more under the influence of an electric field whereas colloidal particles are not allowed to more.
Tyndall effect is the scattering of light by sol particles, which cannot be affected by change on them
