Why True Solutions Do Not Show Tyndall Effect ?​

Answer 1

Answer:

In the true solution the solute is dissolved completely and the particle size is less than 1nm which is not big enough to scatter light ie,show tyndall effect but in the colloidal solution the particles are big enough to scatter a beam of light and thus show tyndall effect.

Because of scattering, the path of the light as well as the particles become visible. But in a true solution, the particle size is so small (less than 1nm) that these particles are not in a position to scatter the light. Therefore, true solution does not show any Tyndall effect.
