Question

The particles in a fine suspension exhibit Brownian movement.

• A. True
• B. False

Answer 1

The correct option is A True

Brownian movement: Brownian movement or Brownian motion is the random zig-zag movement of particles observed under a microscope due to the hitting of the particles with other fast-moving particles.

• It was named after the scientist, Robert Brown who discovered it.
• This phenomenon is most commonly observed in colloids where particles of the dispersed phase collide with the particles of the dispersion medium.
• This phenomenon is not observed for true solutions at all.
• It is observed in the case of suspension where particles of suspensions are fine. It cannot be shown by large suspension particles.
• Dispersed phase: The phase which consists of the colloidal particles present in the smaller quantity.
• Dispersion medium: The phase in which the particles are dispersed and are present in a larger quantity.

Therefore, the given statement is true.
