A) Colloidal particles acquire a charge on their large surface areas.
B) Colloidal particles have large solvation layers.
C) both a and b
D) neither a nor b

Question

Quizplus · Accepted Answer

Both factors contribute to the stability of colloidal particles by preventing them from settling. The large surface area of colloidal particles allows them to acquire a charge through ionization or adsorption, which creates electrostatic repulsion between particles, preventing aggregation and sedimentation. The solvation layer, which is a layer of solvent molecules that surround each particle, also contributes to stability by creating a barrier that hinders particle-particle interactions.
