Gold sol is not a

Explanation:

A sol refers to a colloid solution that is made of solid particles suspended in a continuous liquid medium.

In a sol, the solid is the dispersed phase and liquid is the dispersing medium.

Colloids of such kind are heterogenous or multimolecular in nature.

It was found that the sol made of gold or gold sol is negatively charged and formed by the aggregate of gold atoms. Thus, statements in options B and D are both correct.

It was also found that this sol is not stabilized in solution, in fact it repels the solvent and hence, it is a lyophobic sol. Thus, statement in option A is also correct.

Hence, the statement in option C is incorrect for gold sol.

Final Answer:

Hence, the correct option is C: Macromolecular sol.
