Corrosion of iron in contact with water. One region of the iron acts as the cathode and another region acts as the anode. Fe oxidized at anode region of metal Fe-Fe+ + 2e Water drop [Select] Fe+ (aq) Electrons from Fe oxidation migrate to region acting as cathode e Fe+ axidized to Fe+, rust (Fe,O) forms O + 4H + 4e 2 HO or O + 2 HO +4e -40H A. What is the oxidizing agent in this corrosion reaction? O, reduced at cathode region B. Will the rate of corrosion be increased or decreased in acidic environments? [ Select] *
