1. Mixture – physical blend of two or more substances
Homogenous
Heterogenous

2. Heterogeneous mixture – components are not distributed evenly
Homogenous mixture – components are not distributed evenly

3. Homogenous mixtures Also called “solutions”
Composed of solutes and solvents
Solute – portion in least quantity, seems to lose identity
Solvent – portion in highest quantity, seems to retain identity

4. Heterogeneous mixtures
Will be able to see multiple phases.
Phase – any part of a sample with uniform composition and properties

5. How would we separate mixtures?

6. 1. Manual Sorting
Separate by color, shape, texture, etc.

7. 2. Filtration
Separates based on size
Separates solids from liquids

8. 3. Magnetism
Separating a magnetic substance from a nonmagnetic substance

9. 4. Chromatography
Separation based on solubility

10. 5. Centrifugation
separates the layers based on density

11. 6. Distillation Can be used to remove impurities from water.
Separation based on different boiling points
Can be used to remove impurities from water.

12. What are the substances that make up mixtures? – Elements and compounds!

13. ATOMS ELEMENTS MOLECULESor
make up

14. ATOMS ELEMENTS COMPOUNDS
-smallest building block
-make up all matter
make up
ELEMENTS
COMPOUNDS
-an atom or collection of atoms that are the same
-may be chemically linked
-1 particle made of 2 or more atoms
-chemically linked in a fixed proportion or or

15. Water → Hydrogen + Oxygen
Compounds can be broken down into simpler substances, but elements cannot.
Sugar → Carbon + Water
Water → Hydrogen + Oxygen

17. Carbonated water is a homogenous mixture
Carbonated water is a homogenous mixture. The solute is carbon dioxide and the solvent is water.
It has one phase. All homogenous mixtures only have one phase.
The solvent could be separated by distillation.
