* Mixtures are combinations of two or more substances where each substance retains its own chemical identity. They are not chemically bonded together.

* Solutions are a special type of mixture where one substance (the solute) dissolves completely into another (the solvent).

* Suspensions are mixtures where particles of one substance are dispersed throughout another but can settle out over time.
