Question

Which type of colloid is the dissolution of sulphur $\left(S_8\right)$?

• A. Associated colloid
• B. Micelle
• C. Multimolecular colloid
• D. Macromolecular colloid

Answer 1

The correct option is C Multimolecular colloid

On dissolution, a large number of atoms or smaller molecules of a substance aggregate together to form species having a size in the colloidal range (1–1000 nm). The species thus formed are called multimolecular colloids. Sulphur sol consists of particles containing a thousand or more of $S_8$ sulphur molecules hence it is the multimolecular colloid.
