Aluminium powder reacts with a solution containing iron(III) ions. The ionic equation is:
Al+Fe3+→Al3++Fe\text{Al} + \text{Fe}^{3+} \rightarrow \text{Al}^{3+} + \text{Fe}Al+Fe3+→Al3++Fe
One species in this equation is oxidised. Name this species, and explain in terms of electrons how the change in its charge shows that it has been oxidised.
