Mercury will displace copper from the solution, Hg + Cu 2+ = Hg 2+ + Cu 2. Cu will displace Hg 2+ from the solution, Cu + Hg 2+ = Hg + Cu 2+ Consider Al + Fe 2 O 3 =Al 2 O 3 + Fe reaction. The standard reduction potentials are: Al 3+ + 3e -> Al E =-1.66 V Fe 3+ + 3e -> Fe E =-0.036 V Is the reaction spontaneous as written and which metal oxidizes easier?
