Consider the following statements related to colloids.
(I) Lyophobic colloids are not formed by simple mixing of dispersed phase and dispersion medium.
(II) For emulsions, both the dispersed phase and the dispersion medium are liquid.
(III) Micelles are produced by dissolving a surfactant in any solvent at any temperature.
(IV) Tyndall effect can be observed from a colloidal solution with dispersed phase having the same refractive index as that of the dispersion medium.

Detailed Solution

Lyophobic colloids are not formed by simple mixing of dispersed phase and dispersion medium. These are prepared by special methods.

Emulsions are colloids of liquid dispersed phase and liquid dispersion medium.

Micelles formation occurs when temperature is above Kraft temperature ad concentration above CMC

Tyndall effect can be observed when the refractive indices of the dispersed phase and dispersion medium differ greatly in magnitude.
