Chapter 11, Problem 12DQ

Look up the reduction potential for ${\text{Fe}}^{\text{3+}}{\text{to Fe}}^{\text{2+}}$ . Lookup the reduction potential for ${\text{Fe}}^{\text{2+}}$ to Fe. Finally, look up the reduction potential for ${\text{Fe}}^{\text{3+}}$ to Fe. You should noticethat adding the reduction potentials for the first twodoes not give you the potential for the third. Why not?Show how you can use the first two potentials to calculatethe third potential.
