  • Describe and give examples of various types of solutions. Include: all nine possible types
  • Describe the structure of water in terms of electronegativity and the polarity of its chemical bonds.
  • Explain the solution process of simple ionic and covalent compounds, using visual, particulate representations and chemical equations.
Include: crystal structure, dissociation, hydration
  • Construct, from experimental data, a solubility curve of a pure substance in water. Differentiate among saturated, unsaturated, and supersaturated solutions.
Use a graph of solubility data to solve problems.
Explain how a change in temperature affects the solubility of gases.
  • Explain how a change in pressure affects the solubility of gases.
  • Explain freezing-point depression and boiling-point elevation at the molecular level.

Examples: antifreeze, road salt…

  • Solve problems involving calculation for concentration, moles, mass, and volume.
  • Prepare a solution, given the amount of solute (in grams) and the volume of solution (in millilitres), and determine the concentration in moles/litre.
  • Solve problems involving the dilution of solutions.
    Include: dilution of stock solutions, mixing common solutions with different volumes and concentrations
  • Perform a dilution from a solution of known concentration.
