What volume of oxygen gas at STP must be consumed to produce the corrosion of 200 g of iron? Hint. Fe- Fe2+ +2e (one mole of Fe produces 2 moles of electrons) 40H 02+2H20+4e (42 mole O2 = 1 mole Fe) V=nRT/p =(8.314J/mol)
Science behind corrosion-test
Corrosion is defined as an activity that transforms refined metals into more chemically stable forms such as oxide, hydroxide, carbonate, or sulfide. It refers to the slow decomposition of things (typically metals); thanks to chemical and/or electrochemical reactions with their surroundings. Corrosion engineering is the science of preventing and controlling corrosion.
