1. Concentration of a Solution

2. What is a Solution? A solution is a homogeneous mixture
A homogeneous mixture is formed by one or more solutes and a single solvent
Solute: the substance that is dissolved
Solvent: the substance that does the dissolving
In a solution, you cannot SEE the difference between the solute and solvent particles
A solution looks as though it is only made of 1 substance, although it is really made up of 2 or more substances.

3. Example of a solution? Kool- Aid!!!
How do you make a glass of Kool-Aid?
Measure a small amount of Kool-Aid powder into a glass
Add cold water to the glass and stir
Enjoy!
What is the solute and solvent in Kool-Aid?
Solute: Kool-Aid powder
Solvent: water

4. What is concentration?
The concentration of a solution is the ratio of the amount of solute to the total quantity of solution
Concentration = quantity of solute
quantity of solution (not solvent)

5. Concentrated solution
A concentrated solution contains large amounts of solute in comparison to the volume of the solution
So let’s say you combine 4 spoonfuls of Kool-Aid and 1 cup of water in a glass, your solution would look very dark and taste very sweet.
this is a concentrated solution

6. Dilute solution
A dilute solution contains small amounts of solute in relation to the volume of a solution.
If you combine only 1 spoonful of Kool-Aid to the same volume of water (1 cup), your solution would appear lighter and would not taste as sweet
This is a dilute solution

7. Dilute vs. Concentrated

8. Most concentrated
Less concentrated
Least concentrated

9. Solute varies, solvent costant
Least concentrated
Less concentrated
