Answer :

Brownian movement :

It involves motion of colloidal particles in zig-zag paths. It is DUE to MOVING molecules of the dispersion medium which are constantly COLLIDING with colloidal particles.

  • It is observed in ordinary suspension.
  • It offers a visible proof of the RANDOM kinetic motion of molecules in a liquid.
  • It PROVIDES a direct demonstration of ceaseless motion of molecule as postulated by kinetic theory.
  • It provide stability to colloidal sol by not allowing them to settle down.
