☢️In a sol, all sol particles are continuously bombarded by the molecules of the dispersion medium on all its sides. The impacts are, however not equal in every direction. As a result, the sol particles show random or zig-zag movements. This random or, zig-zag motion of the colloidal particles in a sol is called Brownian movement or Brownian motion.
