Question

Which one of the following is an example for multimolecular colloid?

• A. Aqueous starch sol
• B. Aqueous enzyme sol
• C. Alcoholic polystyrene sol
• D. Aqueous sol of sodium lauryisulphate
• E. Sulpur sol in water

Answer 1

The correct option is E Sulpur sol in water

When a large number of atoms or small molecules (having diameters of less than 1nm) of a substance combine together in a dispersion medium to form aggregates having size in the colloidal range, the colloidal solutions thus formed are called multimolecular colloids.

Sulphur sol (lyophobic sols) in water is an example of multimolecular colloid.

Hence, option $E$ is correct.
