  □

I can identify the oxidation and reduction half reactions in a redox reaction.

  □

I can determine the oxidation number of atoms.

  □

I can write balanced chemical equations for oxidation-reduction reactions using the oxidation number method.

  □

I can write balanced chemical equations for oxidation-reduction reactions using the half-reaction method.

  □

I can use a table of redox half-reactions and reduction potentials to predict and write the net redox reaction for the spontaneous reaction that occurs in a mixture of substances.

  □

I can describe the hydrogen half-cell, and explain its use as a reference cell.

  □

I can analyse the processes in galvanic cells, and draw labelled diagrams of these cells to show the oxidation or reduction reaction that occurs in each of the half-cells, the direction of electron flow, the anode and cathode, the cell potential, and the direction of ion migration.

  □

I can build a galvanic cell and measure its cell potential.

  □

I can explain the corrosion of metals in terms of an electrochemical process, and describe some corrosion-inhibiting techniques.
