C
Electro-osmosis
D
Tyndall effect
Answer
Brownian movement
Explanation
Solution
Brownian motion: It is the zig-zag motion of colloidal particles in a dispersion medium. Tyndall effect: It is the phenomenon of scattering of light due to colloidal particles. Electrophoresis: It is a technique used in laboratories in order to separate macromolecules based on size. Electro-osmosis: It is the motion of liquid induced by an applied potential across a porous material, capillary tube, membrane, micro-channel or any other fluid conduit.
