Question

True solution does not show Tyndall effect. Give reason. [Uttarakhand 2019]

Answer 1

Answer:

Yes it is true.Let me clear one thing,true solutions are also called homogenous mixtures

Explanation:

In true solutions,the solute and.the solvent gets mixed so uniformly that breaks the solute molecules/particles into finer and finer particles.As there is no obstacle in between,the light passes in a straight line without rebounding in any direction.

E.g-sugar and salt solution.

Answer 2

It works on the principle that light beams scatter due to the presence of large colloidal particles in the solution which separate the light however in a true solution the particles are not as large enough to scatter the light particles, that is why Tyndall effect is not seen in true solution.

Hope it helps :)
