Understand the definition of a homogeneous mixture: it is a mixture that has a uniform composition and appearance throughout, meaning you cannot distinguish the different components with the naked eye.
Recall the common types of mixtures: suspensions, colloids, and solutions. Suspensions are heterogeneous mixtures where particles settle out over time. Colloids have particles dispersed throughout but are not completely uniform at the microscopic level.
Recognize that compounds are pure substances made of two or more elements chemically combined, not mixtures.
Identify that solutions are homogeneous mixtures where the solute is completely dissolved in the solvent, resulting in a uniform composition throughout.
Conclude that the term 'solutions' is another name for homogeneous mixtures because they exhibit uniformity at the molecular level.
