What are the two types of mixtures?

• A. Homogeneous and pure
• B. Homogeneous and heterogeneous mixtures
• C. Solids and liquids
• D. Liquid and gas

Answer: (B)

Mixtures are classified by how evenly their components are distributed. In a homogeneous mixture the composition is uniform throughout, so you can’t see separate parts. In a heterogeneous mixture the components are not evenly mixed, and you can often spot different regions or substances. This two-type idea—homogeneous vs. heterogeneous mixtures—is why the correct choice is that pair. The other options mix up concepts: a pure substance isn’t a mixture, and solids/liquids or liquids/gases describe states of matter rather than how well the components are mixed. For example, saltwater is typically a uniform homogeneous mixture, while a salad is a heterogeneous mixture with visible separate ingredients.
