Question:

The electrochemical processes that occur in the corrosion of iron are represented by the half-reactionsFe(s)  Fe+(aq) + 2e- O(g) + 4H+ (aq) + 4e 2HO(l)

(a) Write the overall reaction.

(b) What is the standard potential for the overall chemical reaction?

(c) Natural water has a pH of about 5.9, and air is 0.21 mol fraction oxygen. If the concentration of iron(II)
in the water is 5 × 10-5 M, what is the potential of the corrosion reaction in the presence of air and natural water at 1 atm pressure and 298 K?
