Aluminium reacts with iron(III) oxide. The two half equations for the reaction are Al→Al3++3e−\text{Al} \rightarrow \text{Al}^{3+} + 3\text{e}^-Al→Al3++3e− and Fe3++3e−→Fe\text{Fe}^{3+} + 3\text{e}^- \rightarrow \text{Fe}Fe3++3e−→Fe. Which statement is correct?
Aluminium is reduced and iron ions are oxidised.
Aluminium is oxidised and iron ions are reduced.
Aluminium ions are reduced and iron is oxidised.
Aluminium ions are oxidised and iron is reduced.
