Look up the reduction potential for Fe3 to Fe2. Look up
Chapter 18, Problem 12(choose chapter or problem)
Look up the reduction potential for Fe3 to Fe2. Look up the reduction potential for Fe2 to Fe. Finally, look up the reduction potential for Fe3 to Fe. You should notice that adding the reduction potentials for the first two does not give the potential for the third. Why not? Show how you can use the first two potentials to calculate the third potential. 13
