1. Solutions

2. Common Solutions
Air
Shampoo
Coffee
Gasoline
Cough Syrup

3. Key Terms Solution-a homogeneous mixture
Solvent-substance present in the largest amount
Solute-other substances
Electrolytes-solutions that conduct electricity
Nonelectrolytes-solutions that do not conduct electricity

4. Example
When we dissolve a teaspoon of sugar in a glass of water, what is the solute and solvent?

5. This is an aqueous solutions because water is the solvent
Answers
Sugar-solute
Water-solvent
This is an aqueous solutions because water is the solvent

6. Important rule in Solutions
Like dissolves like

7. Saturated solution-solution has as much solute as will dissolve at a given temperature
Unsaturated solution-solution that has not reached the limit of solute that will dissolve in it
Supersaturated solution-solution that contains more dissolved solute than a saturated solution

8. Strength of Solutions
Concentrated solution-has a large amount of solute dissolved
Dilute solution-small amount of solute
To find the concentration of solutions we use Molarity (M) and molality (m)
