4. Pure Substances
Pure Substance: is made up of one type of matter and has a
unique set of characteristics or properties.
For example, aluminum foil, baking soda, and distilled water
are all pure substances. You cannot separate them into
different substances.

5. Mixtures
Mixtures: are when two or more substances combined
together
 Mechanical Mixture (Heterogeneous): Some or all
particles can be seen and be separated (Ex. Salad)

6. Mixtures
 Solution (Homogeneous): Not separate visibly, looks as
though one is dissolved in another (Ex. coffee)
A substance dissolved in water is called an aqueous solution

7. Mixtures
 Suspension: Mixture where tiny particles of one substance
are held within another. Substances can be separated by
centrifuging or filtration. (Ex. Salad dressing)

8. Mixtures
 Colloid: Cloudy mixture, where the particles are
suspended and difficult to separate (Ex. white milk)
Note: chocolate milk is a suspension because it will
separate if you leave it long enough
