Corrosion kinetics in acidic solutions shows the rate of corrosion of Fe is more than Zn, although the potential reduction of iron is more than Zinc. Why?
Added by Jessica S.
Step 1
Corrosion is an electrochemical process that involves the oxidation of a metal (loss of electrons) and the reduction of a species in the environment (gain of electrons). In this case, we are comparing the corrosion of iron (Fe) and zinc (Zn) in acidic solutions. Show more…

1- Order the following galvanic cells in terms of the rate of corrosion (from highest to lowest). a) Zn & Ag b) Co & Ni c) Zn & Fe d) Zn & Cu 2- Which one (A or B) gives a higher corrosion rate? Why? (EºZn = -0.76 , Eºfe = -0.4) 3- Corrosion kinetics in acidic solutions shows the rate of corrosion of Fe is more than Zn, although the potential reduction of iron is more than Zinc. Why?
