Among the following, correct statement is :

A. Brownian movement is more pronounced for smaller particles than for bigger-particles
B. Sols of metal sulphides are lyophilic
C. Hardy Schulze law states that bigger the size of the ions, the greater is its coagulating power
D. One would expect charcoal to adsorb chlorine more than hydrogen sulphide.

Answer

A

Explanation

Brownian movement is the random motion of particles suspended in a fluid (a liquid or gas) resulting from their collision with the fast moving atom or molecules in the liquid or gaseous state of the matter. That means smaller particles are responsible for the Brownian movement than for bigger particles.
