- BBrownian movement is more pronounced for smaller particles than for bigger-particles.
- Cone would expect charcoal to adsorb chlorine more than hydrogen sulphide.
- DHardy Schulze law states that bigger the size of the ions, the greater is its coagulating power.
Correct answer
B. Brownian movement is more pronounced for smaller particles than for bigger-particles.
Step-by-step solution
Brownian movement is the random motion of particles suspended in a fluid (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.
