Which statement correctly describes a solution?

• A. A solution is a homogeneous mixture of two or more substances that appear to be one substance.
• B. A solution is a mixture with visible parts and is not uniform.
• C. A solution is a pure substance with a fixed composition.
• D. A solution is a solvent that cannot mix with solute.

Answer: (B)

A solution is a homogeneous mixture, meaning its parts are spread out so evenly that you can’t see separate substances and the mixture looks like one substance. The key idea is uniform composition throughout the whole sample, which is why sugar dissolved in water or salt dissolved in water appears like a single, clear liquid. This is different from a mixture that shows visible parts and isn’t uniform, such as cereal in milk or sand in water, where you can see different materials and the distribution isn’t the same everywhere. A pure substance with a fixed composition isn’t a mixture at all—it’s something like pure water or pure salt. And if two substances don’t mix together, forming separate layers or blobs, that isn’t a solution either. So the statement that describes a solution best is the one that emphasizes a uniform, single-substance appearance.
