Unit 3 Exam Review Made by Ms. Manhart’s classes
2
Solutions Solvent & Solute Gabriela and Brianna
3
Definitions Solutions: They are the best mixed mixtures. They have the smallest particles. They stay suspended and they are clear (see through). Solute: Is the part that gets dissolved and could be more than one substance in a mixture. Solvent: Is the greatest amount and does the dissolving.
4
Solution: Salt Water Solvent: WaterSolute: Salt
5
Kool Aid Solvent: WaterSolute: Powder
6
Lemonade Solvent: Water Solute: Sugar and Lemon Juice
7
Hot Chocolate Solvent: MilkSolute: Chocolate Powder
8
Crystal Light Solvent: WaterSolute: Powder
9
Colloids vs. Suspensions By Brianna M. and Gwen D.
10
Colloids A mixture with medium particles that you can see with a microscope. The particles are suspended within the substance. The substance is translucent and it scatters light. Example: Fog or Smoke
11
Suspension A mixture with large particles that are visible to the bare eye. The particles settle to the bottom and are opaque. Example: Sand in water, snow globes or salad dressing
12
Fog- Colloid
13
Milk- Colloid
14
Smoke- Colloid
15
Sand in water- Suspension
16
Snow Globes- Suspension
17
Salad Dressing- Suspension
18
Colloids vs. Suspensions
19
Colloid A mixture containing small, undissolved particles that do not settle out.
20
suspension A mixture in which particles can be seen, and easily separated by settling or filtration.
21
Example 1 Salt water is an example of a suspension. The salt particles will eventually settle to the bottom.
22
Example 2 Salad dressing is an example of a suspension. This is because a the particles with a higher density fal to the bottom
23
Example 3 Milk This is because the substances in milk will not settle out, and cannot be filtered out.
24
SOLUTES AND SOLVENTS (SOLUTIONS) By:Josey, Alex and Cecilla
25
THE SOLUTION SONG http://www.youtube.com/watch?v=3G472AA3SEs
26
SOLUTES Solutes:The substance that gets disolved. They are things that are soluble!
27
EXAMPLES OF SOLUTES Examples: Lemonade and Water The lemonade powder is what is being dissolved. The water is doing the dissolving because when the powder is all gone the mixture becomes LEMONADE!
28
EXAMPLES OF SOLUTES Example: Sugar and Water Sugar is an example of a solute because sugar is what gets dissolved in water.
29
EXAMPLES OF SOLUTES Example: Milk and Hot chocolate When you mix hot chocolate powder with warm milk you create HOT CHOCOLATE!
30
SOLVENTS Solvent:Largest part of a solution: does the disolving.
31
EXAMPLES OF SOLVENT THIS DOES THE DESSOLVING
32
Homogeneous vs. Heterogeneous
33
Heterogeneous: You can see the different parts of the substance. Can only be a mixture. Homogeneous: You can’t see any different parts of the substance. Can be either a mixture or a compound.
34
Homogeneous Examples

Heterogeneous Examples
36
Colloids, Suspension, or Solution By Aiden and Aliea
37
Colloids Medium sized particles Cant see individual particles Particles stay suspended Translucent-allows light to pass through but disrupts images.
38
Fog
39
Milk

Shaving Cream
41
Smoke
42
jello
43
Suspension Large sized particles Can see particles easily Particles settle to the bottom of mixture Cannot see through them
44
Muddy Water
45
Snow Globe
46
Salad Dressing
47
Solar System
48
Dust
49
Solution Small sized particles Cannot see individual particles Particles stay suspended Homogeneous

Test Review Woo who!!!!!!!!?!!! Chemical and Physical Changes
54
Physical changes and Chemical changes. A physical change is any change that changes the appearance but not the chemical composition. A chemical change is a change in matter that makes one or more new substances.
55
Physical Change Add food coloring to water.
56
Physical Change Cutting a cucumber.
57
Physical Change Melting butter.
58
Chemical Change Burning a log.
