Vedclass · Answer

(A) . The Tyndall effect is a phenomenon where light is scattered by colloidal particles,which is not observed in true solutions. Thus,it is used to distinguish between them. This statement is correct.$B$. Zeta potential is the potential difference between the fixed layer and the diffused layer of ions surrounding the colloidal particle,which influences the stability and movement of particles in an electric field. This statement is correct.$C$. Brownian motion is inversely proportional to the viscosity of the medium. If the viscosity is very high,the Brownian motion becomes slower,not faster. This statement is incorrect.$D$. Brownian motion is a random zig-zag motion of colloidal particles that prevents them from settling down due to gravity,but it does not stabilize the sol; rather,it is the charge on the particles that provides stability. This statement is incorrect.Therefore,the correct statements are $A$ and $B$.
