Question

Gold sol is an example of:

Answer 1

Multimolecular sol:

1. Sol is a type of colloid in which solid particles are dispersed in a liquid medium.
2. The type of sol in which a large number of small molecules (having diameters of less than $1\mathrm{nm}$) of a substance combine together in a dispersion medium to form aggregates is known as a multimolecular sol.
3. Gold sol is a negatively charged sol having diameters of particles less than $1\mathrm{nm}$.

Hence, gold sol is an example of multimolecular sol.
