Is the reaction, \( 2 A l+3 F e^{2+} \rightleftharpoons \) \( 2 A l^{3+}+2 F e \) possible?

1. No, because standard oxidation potential of \( A l<F e \)
2. Yes, because standard oxidation potential of \( A l>F e \)
3. cannot be predicted
4. Yes, because aluminium is a strong oxidising agent

Correct answer: Yes, because standard oxidation potential of \( A l>F e \)

Solution

Aluminium has a higher standard oxidation potential than iron, so Al is more readily oxidized while Fe2+ is reduced to Fe. That makes the overall redox reaction spontaneous in the forward direction.
