6.Why is painting a metallic surface not considered an effective way to stop corrosion? a. the paint can cause the corrosion b. paint is acidic and will react with the metal c. any chip or crack in the paint can lead to corrosion d. lead based paints can damage the metallic surface the paint is designed to protect e. moisture and oxygen can penetrate the painted surface
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.
