7. How long has a current of 5 amperes to be applied through a solution of copper nitrate to coat a metal surface of 30 cm2 with 0.008 cm thick layer?
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.
