Objectives

You have completed this lesson when you can:

1. Express concentrations of solutions in weight percent, volume percent, or "weight/volume" percent.

2. Define molarity and calculate molarity, moles of solute, or volume of solutions when given two of these three quantities.

3. Calculate the new molarity when the amount of solvent in a solution is changed (dilution).

4. Determine species concentrations (and amounts) in ionic solutions given the solution concentration.

5. Use colorimetry to determine the concentration of colored solutions.

6. Given that there are several ways of expressing the concentration of a solution, list the advantages of each and describe the situations in which each is most useful.

7. Write solubility product expressions for ionic compounds.

8. Calculate the numerical value of solubility product constants given the ion concentrations at saturation or the solubility of the compound.

9. Calculate the concentration of one ion in a saturated solution given the concentrations of the other ions and the value of the solubility product constant.

10. Calculate the solubility of an ionic compound given its solubility product constant value.
