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.

Copper corrodes in water via the overall reaction:.
a.) Separate this overall reaction into anodic and cathodic half-cell reactions.
b.) Plot the minimum concentration of dissolved Cu2+ ions at which Cu(OH)2 would be expected to precipitate at 25 C as a function of pH from 7 to 14. Cu(OH)2 has a solubility product of 2.2 x 10^-20 at 25 C.
