Solution:

I. Sulphur sol is multimolecular colloid.

II. For Tyndall effect to be observed diameter of dispersed particles should not be much smaller than the wavelength of the light used.

III. Peptisation is the process of forming stable colloid by using an electrolyte to break up a precipitate and dispersed into the colloids hence, given statement is wrong about peptisation.

IV. Eosin and gelatin are examples of negatively charged sol.
