Learning Goals:
Be able to…
4.1 Aqueous Solutions/ Electrolytes:
1. Predict whether a substance is a nonelectrolyte, strong electrolyte, or weak electrolyte
from its chemical behavior.
2. Predict the ions formed by electrolytes when they dissociate or ionize.
4.5 Concentrations of Solutions:
3. Calculate molarity, solution volume, or number of moles of solute given any two of these
quantities.
4. Calculate the volume of a more concentrated solution that must be diluted to obtain a
given quantity of a more dilute solution.
13.1,2,3 Solutions:
5. Describe the energy changes that occur in the solution process in terms of the solutesolute, solvent-solvent, and solute-solvent attractive forces; describe the role of disorder
in the solution process.
6. Rationalize the solubilities of substances in various solvents in terms of their molecular
structures and intermolecular forces.
7. Describe the effects of pressure and temperature on solubilities.
13.4 Concentration Expressions:
8. Define mass percentage, parts per million, mole fraction, molarity, molality, and calculate
concentrations in any of these concentration units.
9. Convert concentration in one concentration unit into any other (given density of the
solution where necessary)
13.5 Colligative properties:
10. Determine the concentration and molar mass of a nonvolatile non-electrolyte from its
effect on the colligative properties of a solution.
11. Explain the difference between the magnitude of changes in colligative properties caused
by electrolytes compared to those caused by nonelectrolytes.
12. Describe effects of solute concentration on the vapor pressure, boiling point, freezing
point, and osmotic pressure of a solution, and calculate any of these properties given
appropriate concentration data.
13.6 Colloids:
13. Be able to describe how a colloid differs from a true solution
Main Goals restated/made more concise:
1. Perform calculations with different solution concentrations such as molarity, mass
percent, molality, and mole fraction.
2. Discuss the effects of temperature, pressure, and structure on solubility.
3. Perform calculations with Raoult’s law
4. Understand colligative properties such as boiling point elevation, freezing point
depression, and osmotic pressure.
5. Use colligative properties to determine the molar mass of a solute.
AP Tip: Questions from this section could appear in both the MC and FRQ section. Questions
on the solubility or miscibility of substances in one another may appear in the essay section.
Questions involving the determination of molar mass by freezing point depression could also
appear in the lab essay.
