SCH4U - Chemistry 12 (2024-25) - A

Acids and bases are a class of chemicals that have unique properties and characteristics that you will have learned about in many of your chemistry courses up to this point.  These chemicals are abundant in both natural and synthetic environments and play a key role in many biological processes.  Acids and bases exist in a state of equilibrium that is characterized by the degree of ionization of hydrogen or hydroxide ions.  In this lesson you will learn about the equilibrium constants that characterize acids and bases and the different ways we can measure and quantify this equilibrium.

Learning Goals:

• Explore the properties of acids & bases.
• Discover the relationship between acid-base reactions and equilibrium constants.
• Investigate titration experiments and their use in determine the concentration of acids and bases.

Success Criteria:

• I know I have achieved the goals for this lesson when I can:
  • Solve problems relating to acid-base equilibrium.
  • Use acid-base titration data to solve problems.
  • Use the ionization constant of water to calculate pH, pOH, [H+] and [OH-]
