This document defines and provides examples of homogeneous, heterogeneous, and concentrations in mixtures. A homogeneous mixture has all parts evenly distributed with no visible individual components, like soda. A heterogeneous mixture is the opposite, with components not evenly spread and visible throughout, like trail mix. Concentration refers to the amount of a substance mixed with another, with the solvent dissolving the solute, and higher concentrations containing larger amounts of solute.
