Question

Colloidal sols shows brownian movement . Does true solution also shows ? If yes or no then"why"?

Answer 1

In truesolution Particles will not show brownian movements..

Colloids show Brownian movement. In colloids, the dispersed 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 dispersed particles show random or zig-zag movements. This random or, zig-zag motion of the colloidal particles is called Brownian movement or Brownian motion.
