Q17 / 90 · JEE Main 2017 (08 Apr Online) · Chemistry

Among the following, the correct statement is:

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

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.

Hence, the correct answer is option: 'B'.
