Answer 1

Tyndall effect is shown by colloidal solution.
Tyndall effect refers to the scattering of light by colloidal particles. The intensity of the scattered light depends on the difference in the refractive index of the dispersed phase and the dispersion medium. The larger the difference, the greater will be the intensity of the scattered light.

In lyophobic sols, the particles are not as highly solvated as in lyophilic sols. So, the difference in refractive index between the particles and the medium is quite large in lyophobic sols. Therefore, the Tyndall effect is more pronounced in lyophobic sols.
