3. Write the electrochemical half-cell reactions for oxidation and reduction during uniform corrosion in the following: (Also indicate if corrosion is possible) a. Corrosion of Aluminum in air free sulfuric acid (i.e., Assume there is no oxygen in the solution) b. Iron in air free acid ferric sulfate solution (assume no O2 in the solution) Hint Fe3+ to Fe2+ reaction is possible due to the presence of the ferric ions c. Carbon steel in aerated seawater (With O2 in the solution, i.e., ORR in neutral or alkaline solution) Assume that FeFe2++2efor carbon steel. d. Zinc in hydrochloric acid solution that is saturated with oxygen
