Define the following terms:
(a) Coagulation
(b) Associated colloids
(c) Brownian movement
(a) Coagulation : The process of settling of the colloidal particles is called coagulation.
(b) Some substances behaves as strong electrolyte at low concentration and forms colloidal solution. At higgh tempertaure, aggregate particles formed such colloidal solution as assoiciated colloids.
(c) Browian movement : Observing under powerful microscope particles in the colloidal solution appears to be in the random zig - zag motion. Such motion is called as Brownian movement.
