Iron galvanized with zinc is cathodically protected from corrosion. This is because?
zinc has a more positive oxidation potential than iron
zinc has less positive oxidation potential than iron
bith have the same oxidation potential
zinc is harder than iron
Correct answer is A
Iron galvanized with zinc is cathodically protected from corrosion because Zinc has a more positive oxidation potential than iron. This means that Zinc will preferentially corrode, acting as a sacrificial anode.
