Chapter 15

[Note: Programmable and graphing calculators may be used if there are no formulas or data that will help you with this quiz.]

KNOW THE FOLLOWING CONCEPTS:

  • how solutes and solvents relate to solutions
  • homogeneous vs. heterogeneous mixtures
  • solutions: unsaturated vs. saturated vs. supersaturated
  • the dissolving process on a molecular level
  • mass percent vs. mole fraction
  • molarity vs. molality
  • solubility rules (in water)
  • solubility based on solvent type: “like dissolves like”
  • factors affecting solubility of gases
  • factors affecting solubility of solids
  • solution stoichiometry
  • colligative properties, such as freezing point depression and boiling point elevation

BE ABLE TO ANSWER PROBLEMS INVOLVING:

  • calculating mass percent, mole fraction, molarity, or molality given relevant information
  • calculating problems involving ion concentration
  • dilutions
  • solution stoichiometry
  • colligative properties, such as freezing point depression and boiling point elevation
