Module 6 | Acid/base reactions

Content 3: Quantitative analysis

Lesson 1 | Titrations

  • conduct practical investigations to analyse the concentration of an unknown acid or base by titration

Lesson 2 | Titration curves

  • investigate titration curves and conductivity graphs to analyse data to indicate characteristic reaction profiles, for example:
    – strong acid/strong base
    – strong acid/weak base
    – weak acid/strong base (ACSCH080, ACSCH102)

  • model neutralisation of strong and weak acids and bases using a variety of media

Lesson 3 | Modelling neutralisation

  • model neutralisation of strong and weak acids and bases using a variety of media

Lesson 4 | Dissociation constants of acids

  • calculate and apply the dissociation constant (Ka) and pKa (pKa = -log10 (Ka)) to determine the difference between strong and weak acids

Lesson 5 | Acid/base analysis techniques

  • explore acid/base analysis techniques that are applied:

    – in industries

    – by Aboriginal and Torres Strait Islander Peoples

    – using digital probes and instruments

Lesson 6 | Preparation of a buffer

  • conduct a chemical analysis of a common household substance for its acidity or basicity (ACSCH080), for example:
    – soft drink
    – wine
    – juice
    – medicine

  • conduct a practical investigation to prepare a buffer and demonstrate its properties (ACSCH080)

Lesson 7 | Buffers in natural systems

  • describe the importance of buffers in natural systems (ACSCH098, ACSCH102)
