Assertion: Colloidal solutions do not show brownian motion.
Reason : Brownian motion is responsible for stability of sols.
Assertion: Colloidal solutions do not show brownian motion.
Reason : Brownian motion is responsible for stability of sols.
The correct option is B Assertion is incorrect but reason is correct.
The phenomenon of Brownian motion was first observed by Robert Brown in the form of random zig-zag motion of pollen grains suspended in water.
The random or zig-zag motion of the colloidal particles in a sol is called Brownian motion or Brownian motion.
Also colloidal particles in a sol are continuously bombarded by the molecules of the dispersion medium on all sides due to which some impacts are created.
hese impacts are not equal in every direction. As a result, the sol particles show random or zig-zag movements. So Colloidal particles show Brownian motion and it is responsible for the stability of the sols.
Hence, Assertion is incorrect but the reason is correct.
