Tyndall effect is more effectively observed in lyophobic colloids or suspension? .. ...ans is lyophobic colloids

Itzz not matter that in colloidal solution what is going between dispersed phase and dispersion medium but fact is that Whoose molecule is bigger so that it show tyndall effect that is suspension

Above ans is wrong correct ans is lyophobic becoz tyndall effects both depend upon size nd no. Of particle present that is between dispersed phase and dispersion medium have small attractions and so no. Is high nd size too...

The extent of scattering due to tyndal effect i large when there is a large difference in the refractive indices of the dispersed phase and dispersion medium. Since in lyophobic colloids, the degree of solvation is very low, there is a big difference between the refractive indices and hence tyndall effect is prominent.

in lyophilic sol the different in refractive indice is almost neffect ingligible and hence tyndall effect is weak

Tyndall effect refers to the scattering of light by colloidal particles.

The intensity of the scattered light depends on the difference in the refractive indices of the dispersed phase and the dispersion medium. Larger the difference, 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 indices between the particles and the medium is quite large in lyophobic sols. Therefore, they show distinct Tyndall effect.
