The correct statements about the properties of colloidal solutions are
A. Tyndall effect is used to distinguish between a colloidal solution and a true solution
B. Zeta potential is related to movement of colloidal particles
C. Brownian motion in colloidal solution is faster if the viscosity of the solution is very high
D. Brownian motion stabilises the sols
Show Hint
Remember the key properties of colloids:
- \textbf{Tyndall Effect:} Scatters light (diagnostic test).
- \textbf{Brownian Motion:} Random movement due to molecular collisions; prevents settling and aids stability.
- \textbf{Zeta Potential:} A measure of the charge on the particle's surface layer; a high value indicates strong repulsion and high stability.
