Question

Explain Tyndall effect and Brownian movement with suitable diagram.

Accepted Answer

When a strong beam of light is focused on a colloidal solution, light is scattered by the colloidal solution and the path of the beam becomes visible. This phenomenon is called as Tyndall effect. The illuminated path is called Tyndall cone. True solution does not show tyndall effect.

When colloidal solution are viewed under powerful microscope, it can be seen that colloidal particles are moving constantly and rapidly in zig-zag directions. This movement is known as Brownian movement. Particles in the dispersion medium collides with each other which results in this motion.
