Which term describes a homogeneous mixture that appears uniform?

• A. Not uniform mixture
• B. A pure substance
• C. Solution
• D. Element plus compound

Answer: (C)

A solution is a homogeneous mixture that appears uniform. In a solution, the substance that dissolves (the solute) is distributed evenly within the substance doing the dissolving (the solvent) at the molecular level, so any sample looks the same throughout. Salt in water or sugar in tea are classic examples you can see or test for yourself.

Not uniform mixtures have visible different parts, like a salad or pepper scattered in water, so they don’t look the same throughout. A pure substance, while it can appear uniform, is not a mixture at all—it's made of only one kind of particle, either an element or a compound. The phrase “element plus compound” isn’t a standard way to describe a single homogeneous mixture, so it doesn’t fit the idea of a solution. Therefore, the term that best describes a homogeneous mixture that looks uniform is a solution.
