What are solutions? Mr. Heffner
1/5/10
What is a mixture? A mixture is…
when 2 (or more) substances are combined
There are two types of mixtures: “things”
Homogenous homo = same Evenly mixed
Examples: Salt water Kool-Aid
Heterogeneous hetero = different Not evenly mixed
Examples: Sand and water Oil and water
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
What is a solution? To make a kool-aid solution,
+ =
solute solvent solution
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
Foldable Make a foldable and define the following terms:
Substance Heterogeneous mixture
Homogeneous mixture Solution Solvent
Solute Solid
Liquid
