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.

In the 1980s, U.S. Fish and Wildlife Service researchersfound high mortality among newborn coots and ducks in parts ofCalifornia. U.S. Geological Survey scientists later found thecause to be a high selenium concentration in agricultural drainagewater. Balance the half-reactions in the selenium cycle:
