Detailed explanation-1: -Colloids are unlike solutions because their dispersed particles are much larger than those of a solution. The dispersed particles of a colloid cannot be separated by filtration, but they scatter light, a phenomenon called the Tyndall effect.
Detailed explanation-2: -When light is shined through a true solution, the light passes cleanly through the solution, however when light is passed through a colloidal solution, the substance in the dispersed phases scatters the light in all directions, making it readily seen.
Detailed explanation-3: -When light is passed through a colloidal solution it scatters in different directions. This is due to the Tyndall effect. The Tyndall effect is the phenomenon of light scattering by particles in a colloidal solution.
Detailed explanation-4: -The size of colloidal particles is large enough to scatter light while particles of a true solution are too small to scatter light.
Detailed explanation-5: -The phenomenon by which colloidal particles scatter light is called Tyndall effect. The particles of colloids scatter a beam of light passing through it and make its path visible. True solutions do not show Tyndall effect. Scattering of light or Tyndall Effect is exhibited by Colloidal and Suspension particles.
