Module 6 | Acid/base reactions

Content 2: Using Brønsted–Lowry theory

Lesson 1 | Measuring the pH of acids and bases

  • conduct a practical investigation to measure the pH of a range of acids and bases

Lesson 2 | Calculating the pH and pOH of solutions

  • calculate pH, pOH, hydrogen ion concentration ([H+]) and hydroxide ion concentration ([OH]) for a range of solutions (ACSCH102)

Lesson 3 | pH of identical concentrations of strong and weak acids and bases

  • conduct an investigation to demonstrate the use of pH to indicate the differences between the strength of acids and bases (ACSCH102)

Lesson 4 | Conjugate and base pairs

  • write ionic equations to represent the dissociation of acids and bases in water, conjugate acid/base pairs in solution and amphiprotic nature of some salts, for example:
    – sodium hydrogen carbonate
    – potassium dihydrogen phosphate

Lesson 5 | What is the role of water in solutions of acids and bases?

  • construct models and/or animations to communicate the differences between strong, weak, concentrated and dilute acids and bases (ACSCH099)

Lesson 6 | Calculating pH when acids and bases are mixed

  • calculate the pH of the resultant solution when solutions of acids and/or bases are diluted or mixed
