Which term describes a mixture with uniform composition? i.e., a homogeneous mixture

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

Answer: (B)

Uniform composition is the hallmark of a homogeneous mixture. In such a mixture, the components are distributed evenly throughout, so any sample pulled from it has the same proportions and properties, no matter where you sample. This is what makes it indistinguishable on a small scale—the parts blend uniformly. A general mixture can be heterogeneous, where different regions have different compositions (like oil and water). A solution is a specific type of homogeneous mixture formed when a solute dissolves in a solvent, and it still has uniform composition, but the broad term that describes any mixture with uniform composition is a homogeneous mixture. A pure substance, on the other hand, is a single element or compound with a fixed composition, not a mixture. So, the best description for a mixture with uniform composition is a homogeneous mixture.
