5. What are solutions?
Mr. Heffner
1/5/10

6. What is a mixture?
 A mixture is…
 when 2 (or more) substances are combined
 There are two types of mixtures: “things”
Homogenous Heterogeneous
 homo = same  hetero = different
 Evenly mixed  Not evenly mixed
 Examples:  Examples:
 Salt water  Sand and water
 Kool-Aid  Oil and water

7. What is a solution?
 A solution is…
 a homogeneous mixture of 2 (or more) substances.
 made up of a solute and a solvent
 Solutes are the things that are dissolved
 Usually a solid
 Solvents are the things that solutes are dissolved in
 Always a liquid
 Always larger in quantity

8. What is a solution?
 To make a kool-aid solution,
+ =
solute solvent solution

9. Examples
 Is it a solution?
1. sugar and water
2. dirt and water
3. vegetable soup (vegetables & chicken broth)
 For the following solutions, name the solute and the
solvent:
1. Salt water (salt & water)
 Solute = salt
 Solvent = water
2. Soda (syrup, CO2, & water)
 Solute = syrup, CO2
 Solvent = water

10. Foldable
 Make a foldable and define the following terms:
 Substance
 Heterogeneous mixture
 Homogeneous mixture
 Solution
 Solvent
 Solute
 Solid
 Liquid
