Mixtures can be classified based on how well their components are mixed. They are separable by physical means like filtration or distillation. Heterogeneous mixtures are unevenly mixed and allow visible differentiation of their components, while homogeneous mixtures, such as solutions, are evenly mixed and appear as a single substance. Solutions do not separate over time and cannot be filtered. Suspensions, being heterogeneous, separate into layers and scatter light. Colloids share characteristics with both suspensions and solutions, lacking filtration but behaving homogeneously.

Mixtures • Can be classified by how well the parts of the mixture are mixed • Can be separated by physical means like filtration or distillation
Heterogeneous Mixtures • Not evenly mixed • Can easily see the different parts
Homogenous Mixtures • Evenly mixed • Appear as only one substance (like tap water)
Solutions • Homogeneous mixture • Does not separate into layers over time • Particles don’t settle out • Can’t be filtered • Don’t scatter light
Suspensions • Heterogeneous mixture • Separates into layers over time • Can use filter to separate • Scatter light • Usually cloudy
Colloids • Considered a homogeneous mixutre • Particles in-between a suspension & a solution • Do not separate into layers • Cannot use a filter to separate • Scatter light
What are the main differences between heterogeneous and homogeneous mixtures?
