Solution: a homogeneous mixture of two or more substances. The chemical properties of the components dont change. Solutions, colloids, suspensions. Physical methods such as filtration, freezing, and distillation, can be used to separate mixtures, but not compounds, into their components. Sugar immediately melts into hot coffee, disappearing entirely.
