Solutions

1. Dilution, Dissolution and Evaporation Solutions

2. Dilution, Dissolution & Evaporation • The concentration of a solution ___________________in different ways • Ex: If water is added to a bowl of soup, the taste _______________________ • The soup is ______________; the concentration of the chicken soup is lower

3. Dilution, Dissolution & Evaporation • Ex: If chicken bouillon powder is added , the flavour becomes more intense. • The concentration increased because of the addition of extra solute (_____________________)

4. Dilution, Dissolution and Evaporation • If evaporation takes place the amount of ______________________therefore it will ______________the concentration

5. Effects of various changes on the concentration of a solution

6. Dilution We can solve dilution problems using the following formula _____________________ C1 = original concentration of the solution, before it gets watered down or diluted. C2 = final concentration of the solution, after dilution. V1 = volume before dilution V2 = final volume after dilution

7. Surviving Dilution C1V1= C2V2. By drawing the "X" through the equal sign and filling in the formula with letters of a size permitted by the borders of the "X", it reminds you that : For all dilution problems ____________________________________

8. This makes sense because when we dilute we add more solvent. • This _______________the volume but _____________the concentration

9. Dilution Problems Joe has a 2 g/L solution. He dilutes it and creates 3 L of a 1 g/L solution. How much of the original solution did he dilute?

10. Joe has 20 L of a 2 g/L solution. He diluted it, and created 3 L of a 1 g/L solution. How did he make such a solution.

11. Joe has 20 L of a 2 g/L solution. To this solution he adds 30 L. What is the final concentration of the solution?
