Which term describes a homogeneous mixture that will never settle and has particles too small to be seen?

• A. Heterogeneous mixture
• B. Solution
• C. Colloid
• D. Homogeneous mixture

Answer: (B)

The key idea is that a solution is a type of homogeneous mixture in which the dissolved particles are distributed at the molecular or ionic level and remain evenly spread without settling. Because the solute particles are so small, they can’t be seen with the naked eye, and they stay mixed with the solvent over time, giving a uniform composition throughout. This is why substances like salt in water or sugar in tea look the same throughout and don’t separate into parts. In contrast, a heterogeneous mixture shows visible different parts, and a colloid has larger particles that can scatter light and may not be truly dissolved. So, the description fits a solution.
