Question
9. Corrosion of metals is a serious concern in industries. Some metals are made "rust proof" with the addition of a second metal. For example, galvanized nails are used in construction products outdoors as the nails won't easily rust even moist environments. Galvanized nails are made of iron coated in zinc. a. The oxidation of iron involves the reduction of oxygen gas with water. Find the reduction potential for this half reaction. (You'll need this number to help answer the other parts of this question!) b. The oxidation half reaction involves iron losing electrons. Iron ion, however, has two possible oxidation states. Which ion, Fe2+ or Fe³+, do you predict would form more spontaneously with the half reaction from part a. Explain.
