become more vigorous, than that observed with present finite value of Avogadro's number, for all sizes of the Brownian particles. remain completely unaffected. becomes more vigorous, than that observed with the present finite value of Avogadro's number, only for relatively large Brownian particle.
i) Brownian movement is more pronounced for smaller particles than for bigger ones. ii) Sols of metal sulphides are lyophilic. iii) Schulze-Hardey law states, the bigger the size of the ion, the greater is its coagulating power. iv) One would be expect charcoal to adsorb chlorine more strongly hydrogen sulphide
(a) The zig-zag movement of the small particles suspended in a liquid or a gas is called Brownian movement. (b) These dust particles move in a haphazard way because they are constantly hit by the fast moving particles of air.

i) Which solution shows Brownian movement? ii) Identify the solution that has the particle size greater than 2000 ∘ A. iii) Which beaker contains colloidal solution? iv) Mention the size of the particle present in beaker B. v) Say whether colloidal solution in homogeneous or heterogeneous
British Botanist Robert Brown (1828) found that the pollen grains present in water move in a continuous zig-zag movement. This movement is called Brownian movement. This movement is called Brownian movement.
Brownian motion is the continuous random movement of small particles suspended in a fluid, which arise from collisions with the fluid molecules. When colloidal solutions are viewed under a powerful ultramicroscope, the colloidal particles appear to be in a state of continuous zig-zag motion all over the field of view.
Brownian movement is due to the unequal bombardments of the moving molecules of dispersion medium on colloidal particles. The moving molecules of the dispersion medium continuously attack on colloidal particles from all sides and impart momentum to them. Since the chances of their collisions are unequal, the net driving force on a colloidal ...
Correct option is C. Impact of molecules of the dispresion medium on the colloidal particles. Brownian motion is the random movement of particles in a fluid due to their collisions with other atoms or molecules.
