Exploring Mixtures and their Separation Mind Map
Use this learning tree to open the right concept in the right order. Start with a branch, expand it, then move into the concept page you need next.
Classifying Mixtures
highA mixture is a physical combination of two or more substances in which the components keep their own properties and can usually be separated by physical methods.
When classifying, write both the type and the reason: uniform composition for homogeneous, non-uniform composition for heterogeneous.
Suspensions and Colloids
mediumA suspension is a heterogeneous mixture with large particles that may settle, while a colloid has smaller dispersed particles that do not settle easily and appear fairly uniform.
Use particle size, settling behaviour, filtration, and light scattering for comparison questions.
