Solving Problems with Solutes and Solvents

2. Solution A liquid with a solute dissolved in it
Can have color, but usually transparent
Molecules dissolved are so small light waves do not bounce off of them
lemonade
tea
salt water

3. Solute Molecules that are dissolved in a solvent to make a solution.
Sugar
Salt
CO2

4. Solvent The liquid in which the solute is dissolved. Water Gasoline
Acetone (nail polish remover)
Turpentine (paint thinner)

5. Concentrated
A lot of solute in the solvent

6. examples…
Strong tea
Strong lemonade
Orange Juice Concentrate

7. Dilute
Little solute in a lot of solvent

8. examples…
weak tea
weak lemonade
Orange Juice from Concentrate

9. Soluble vs. Insoluble Soluble - able to dissolve
Insoluble - not able to dissolve

10. Determining % Concentration
90 red (kool aid)
10 white (water)
= 90% kool aid solution
Solute 90 (red)
Solution 100 (total)
= 90 %

11. Determining % Concentration
50 red (kool aid)
50 white (water)
= 50% kool aid solution
Solute 50 (red)
Solution 100 (total)
= 50 %

12. Determining % Concentration
20 red (kool aid)
80 white (water)
= 20% kool aid solution
Solute 20 (red)
Solution 100 (total)
= 20 %

13. diffusion
Both diffusion and osmosis happen because of differences in % concentration.
osmosis
