Explain Tyndall effect and Brownian movement.
i. Tyndall Effect:
When a strong beam of light is focused on a , the beam's path becomes visible. This phenomenon is called as . The illuminated path is called the Tyndall cone. This phenomenon is due to the by colloidal particles.
ii. Brownian movement:
is a kinetic property.
When s are viewed under a powerful microscope, it can be seen that colloidal particles are moving constantly and rapidly in zig-zag directions.
The Brownian movement of particles is due to the unbalanced by the molecules of the dispersion medium.
