If solute particles are very small and do not settle at the bottom, which idea does this support?
Answer and explanation
Correct answer: Nature of a true solution
True-solution particles are extremely small and remain uniformly distributed, so they do not settle under ordinary conditions. A suspension contains larger particles that usually settle on standing. Settling, precipitate formation, or visible layers therefore suggest a different mixture, not the stable homogeneous nature of a true solution.
