What is the overall reaction for the corrosion of iron?
Options
- A2 Fe (s) → 2 Fe2+ + 4 e-
- BO 2 (g) + 4 H+(aq) + 4 e- → 2 H 2 O (l)
- C2Fe(s) → 2Fe2+(aq) + 2 H 2 O (l)
- D2Fe(s) + O 2 (g) + 4H+(aq) → 2Fe2+(aq) + 2 H 2 O (l)
Correct answer
D. 2Fe(s) + O 2 (g) + 4H+(aq) → 2Fe2+(aq) + 2 H 2 O (l)
Step-by-step solution
The overall reaction for the corrosion of iron is"2Fe(s) + O 2 (g) + 4H+(aq) → 2Fe2+(aq) + 2 H 2 O (l)."
