Take a solution, a suspension, a colloidal dispersion in different beakers. Test whether each of these mixtures shows the Tyndall effect by focusing a light at the side of the container.

Answer :

Take three beakers and marked them as A, B and C.


In beaker A take sugar solution, in B chalk powder mixed with water and in C milk, then stir the contents of all the three beakers.


Direct a beam of light from a torch through all the three beakers.


Observation: Path of light is visible in beaker B and C


Now keep all the three beakers undisturbed for few minutes and then again pass the beam of light.


Observation: Path of light is visible only in C.


Conclusion:


● Beaker A: Since sugar is soluble in water so sugar solution form a homogeneous solution and can’t show Tyndall effect.


● Beaker B: Chalk powder is insoluble in water so it will form a non homogeneous mixture and initially the particle can scatter the beam of light but when the particle will settle down they will not show Tyndall effect.


● Beaker C: Milk is a colloid whose particle size is too small to see through naked eyes and this particle can easily scatter the beam of light and thus show Tyndall Effect.
