Which of the following factors causes colloidal particles to remain in solution without settling?
A) Colloidal particles and solvent molecules are of the same size.
B) Colloidal particles have large solvation layers.
C) Colloidal particles and solvent molecules are of the same size and colloidal particles have large solvation layers.
D) None of these are correct.

Question

Quizplus · Accepted Answer

Colloidal particles remain in solution without settling due to their large solvation layers. These layers are formed due to the interaction between the particles and the solvent molecules, which prevents the particles from aggregating and settling out of the solution. Option A is incorrect as the sizes of colloidal particles and solvent molecules may differ. Option C is partially correct, but the main reason for the stability of colloidal solutions is the large solvation layer around the particles. Option D is incorrect as there is a factor that causes colloidal particles to remain in solution.
