Module 1 | Production of materials

Focus 4: Oxidation-reduction reactions are increasingly important as a source of energy

Lesson 1 | Galvanic cells as an energy source

  • Describe and explain galvanic cells in terms of oxidation/reduction

Lesson 2 | Displacement of metals from solutions

  • Explain the displacement of metals from solution in terms of transfer of electrons

  • Identify the relationship between displacement of metal ions in solution by other metals to the relative activity of metals

Lesson 3 | Oxidation states

  • Account for changes in the oxidation state of species in terms of their loss or gain of electrons

Lesson 4 | Galvanic cells

  • Describe and explain galvanic cells in terms of oxidation/reduction reactions

  • Outline the construction of galvanic cells and trace the direction of electron flow

  • Define the terms anode, cathode, electrode and electrolyte to describe galvanic cells

Lesson 5 | Constructing galvanic cells

  • Perform a first-hand investigation to identify the conditions under which a galvanic cell is produced

  • Perform a first-hand investigation and gather first-hand information to measure the difference in potential of different combinations of metals in an electrolyte solution

  • Solve problems and analyse information to calculate the potential requirement of named electrochemical processes using tables of standard potentials and half-equations

Lesson 6 | Chemistry of other cells

  • Gather and present information on the structure and chemistry of a dry cell or lead-acid cell and evaluate it in comparison to one of the following:
    – button cell
    – fuel cell
    – vanadium redox cell
    – lithium cell
    – liquid junction photovoltaic device (e.g. the Gratzel cell)

    in terms of:
    – chemistry
    – cost and practicality
    – impact on society
    – environmental impact
