1. A homogeneous mixture in which the components are uniformly mixed
SOLUTIONS
A homogeneous mixture in which the components are uniformly mixed

2. Terms
Solvent – the substance present in the largest amount in a solution.
The substance that does the dissolving.
Solute – the other substance or substances in a solution.
The substance that is dissolved.

3. Terms Saturated Unsaturated
When a solution contains the maximum amount of solute
Unsaturated
When a solvent can dissolve more solute

4. Few more terms… Concentrated Dilute
When a relatively large amount of solute is dissolved
Dilute
When a relatively small amount of solute is dissolved

5. MOLARITY Molarity-the number of moles of solute per liters of solution
M = molarity = moles of solute
liter of solution

6. The Molarity Triangle
mol M L

7. Calculate the molarity of a solution prepared by dissolving 11
Calculate the molarity of a solution prepared by dissolving 11.5 g of NaOH in enough water to make a 1.50 L solution.

8. Calculate the molarity of a solution prepared by dissolving 1
Calculate the molarity of a solution prepared by dissolving 1.56 g of HCl into enough water to make 26.8 ml of solution.

9. Calculate the number of grams of sodium phosphate required to make 150
Calculate the number of grams of sodium phosphate required to make 150. ml of a 2.5M solution.

10. How many liters of solution are needed to dissolve 5
How many liters of solution are needed to dissolve 5.0 g of hydrochloric acid to make a 3.0 M hydrochloric acid solution?

11. Density and dilutions

12. DENSITY What is the relationship between density and molarity?
The greater molarity of a solution, the __________ dense the solution is.

13. DILUTIONS
M1 x V1 = M2 x V2
Where M = molarity
V = volume

14. Some practice
What volume of 16 M sulfuric acid must be used to prepare 1.5 L of a 0.10 M H2SO4

15. More practice
What volume of 12 M HCl must be used to prepare 0.75 L of a 0.25 M HCl?
