AIM: To demonstrate the phenomenon of Dispersion and Diffusion. DEFINITION: It is a simple physical phenomenon of spreading out of the particles of any substance or solute almost evenly in suitable solvent with the formation of a layer of sediment at the bottom, provided the solvent is not disturbed. THEORY: When any solute is added to a solvent that is allowed to remain undisturbed after the addition of solute, there is tendency on the part of the solute particles to move away from the original concentrated form and try to distribute evenly at the bottom (exhibiting dispersion) before getting evenly distributed between the molecules of solvent (exhibiting diffusion).
