1. Mixtures and Solutions

2. Mixtures two or more materials stirred together
How do you separate mixture?
Hand separation
Screening
Filtering

3. Solutions a special mixture formed when a material dissolves in water
How do you separate solution?
Evaporation

4. Solubility or most soluble
The property of a substance that tells how it dissolves in a liquid.
Which is the most soluble?
Salt
Baking soda
Citric Acid

5. Saturated Solution
is when a solute dissolves in a solvent until no more will dissolve.
How can you dissolve more in a saturated solution?
Heat
Add more solvent

6. Saturated solutions
All saturated solutions made at the same temperature always have the same ………
Concentration.

7. Crystal Regular form Examples: Salt - Citric Acid - Epsom Salt -
Snowflake -

8. Concentration the amount of material dissolved in an amount of liquid.
Mathematically
Which is more concentrated?
1 in 25, 2 in 50, 3 in 100, 4 in 125

9. Dilute to make a solution less concentrated To dilute something:
Add more solvent - water or the liquid

10. Chemical Reactions
When two or more materials (chemicals)are mixed together and a change occurs.
Evidence of a chemical change:
•Fizzing, bubbling, or releasing gas
•Temperature change.
•Forms a new substance. (precipitate)
