Matter Flowchart
MATTER
yes no
Can it be physically separated?
MIXTURE
PURE SUBSTANCE
Is the composition uniform? no
yes
Can it be chemically decomposed? no
yes
Homogeneous Mixture
(solution)
Heterogeneous Mixture
Compound
Element
Colloids
Suspensions

3. Pure Substances Element composed of identical atoms
EX: copper wire, aluminum foil

5. Pure Substances Compound
composed of 2 or more elements in a fixed ratio
properties differ from those of individual elements
EX: table salt (NaCl)

6. Sodium & Chlorine Reaction

7. Mixtures Variable combination of 2 or more pure substances.
Mixtures can be separated by physical means.
Heterogeneous
Homogeneous

8. Mixtures Solution homogeneous very small particles
particles don’t settle
example: rubbing alcohol

9. Solutions A solution has two parts
Solute: The substance being dissolved.
Solvent: The substance that the solute dissolves into.

10. Distillation
Distillation is often used to separate mixtures in solution.

11. Mixtures Colloid heterogeneous medium-sized particles
particles don’t settle
example: milk

12. Centrifuge
Centrifuges are used to separate colloidal mixtures.

13. Tyndall Effect
Solutions and Colloids can be differentiated by shining a light through them.
The particles in a colloid will scatter the light allowing you to see the beam.

14. Tyndall Effect

15. Mixtures Suspension heterogeneous large particles particles settle
example: muddy water

16. Suspension
A suspension is a heterogeneous mixture containing a liquid in which visible particles will settle.
