Which term describes a mixture formed when substances dissolve in another to form a homogeneous mixture?

• A. Solution
• B. Pure substance
• C. Mixture
• D. Element

Answer: (A)

When substances dissolve in another and the result has a uniform composition throughout, that blend is called a solution. The particles are spread evenly, so you can’t distinguish different parts—it's a homogeneous mixture. A pure substance, by contrast, is made of only one kind of particle (either a single element or a compound), not a mix of different substances dissolving together. A mixture is a broader category and can be either uniform or not; when it's formed by dissolving, the specific term for that uniform blend is a solution. An element is a pure substance consisting of one type of atom, not a mixture at all.
