Vedclass · Answer

(B) $I$. Sulphur sol is a multimolecular colloid because it contains a large number of $S_8$ molecules aggregated together. This statement is correct.$II$. For the Tyndall effect to be observed,the diameter of the dispersed particles must not be much smaller than the wavelength of the light used. This statement is correct.$III$. The process of removing a dissolved substance from a colloidal solution by means of diffusion through a suitable membrane is called dialysis,not peptisation. Peptisation is the process of converting a precipitate into a colloidal sol by adding an electrolyte. This statement is incorrect.$IV$. Eosin and gelatin are examples of negatively charged sols. This statement is correct.Therefore,the correct statements are $I, II,$ and $IV$. Hence,option $(B)$ is correct.

List-$I$	List-$II$
$A$. Negatively charged sol	$I$. $Fe_{2}O_{3} \cdot xH_{2}O$
$B$. Macromolecular colloid	$II$. $CdS$ sol
$C$. Positively charged sol	$III$. Starch
$D$. Cheese	$IV$. $A$ gel
