Question

Sulphur sol contains :

• A. discrete $S-$atoms
• B. discrete $S-$molecules
• C. large aggregates of $S-$molecules
• D. water dispersed in solid sulphur

Answer 1

The correct option is C large aggregates of $S-$molecules

Sulphur sol contains an aggregate of thousands of $S_8$ sulphur molecules.

If large number of atoms or smaller molecules of a substance aggregate together to form particles having size in the colloidal range then the colloidal system is known as multimolecular colloid.

Hence, option C is correct.
