Which term describes a homogeneous mixture whose particles are so small they won't settle?

• A. Gases
• B. Pure Substance
• C. Solution
• D. Homogeneous Mixture

Answer: (C)

A solution describes a homogeneous mixture where the particles are dissolved so completely that they are too small to settle out. In a solution, the solute is dispersed at the molecular level within the solvent, making the mixture uniform throughout and preventing separate layers from forming. A classic example is salt dissolved in water, which looks the same all the way through. Gases aren’t described by this term in the same way, since they’re a state of matter and air’s uniformity comes from tiny gas molecules mixing, not from dissolved particles. A pure substance is only one material, not a mix of substances dissolved in each other, and a homogeneous mixture is a broad category that includes solutions but doesn’t specify the dissolved nature of the particles. So the term that best fits a homogeneous mixture whose particles are so small they won’t settle is a solution.
