The corrosion of iron is an electrochemical process that involves the standard reduction potentials given here at 25 oC: Fe2+(aq) + 2e- ⟶  Fe(s)  Eo = -0.44 V O2(g) + 4H+(aq) + 4e- ⟶  2H2O(l)  Eo = 1.23 V a) Calculate the voltage if the reaction occurs at pH = 4.00 but all other concentrations are maintained as they would be in a standard cell. b) For the reaction Fe(OH)2(s) + 2e- ⟶  Fe(s) + 2OH-(aq), Eo = -0.88V. Determine the Ksp of Fe(OH)2.

Question

The corrosion of iron is an electrochemical process that involves the standard reduction potentials given here at 25 oC:

Fe2+(aq) + 2e- ⟶  Fe(s)  Eo = -0.44 V

O2(g) + 4H+(aq) + 4e- ⟶  2H2O(l)  Eo = 1.23 V

a) Calculate the voltage if the reaction occurs at pH = 4.00 but all other concentrations are maintained as they would be in a standard cell.

b) For the reaction Fe(OH)2(s) + 2e- ⟶  Fe(s) + 2OH-(aq), Eo = -0.88V. Determine the Ksp of Fe(OH)2.
