Another way to prevent the corrosion of iron is to exclude oxygen and moisture from its surface with a protective coating.
WebIn the corrosion process, metals get oxidized. Water-works administrators like to make the water slightly alkaline and slightly supersaturated in calcium carbonate in order to maintain a thin coating of solid carbonate on the interior of the pipe which acts to protect it from corrosion. Severe corrosion like this is more common in areas where the water is acidic. Explain how atmospheric corrosion occurs, and how it results in the eating away of metal. Were there any differences between the two? could also be explained by inconsistencies in Since iron has a lower reduction potential than copper, it will be oxidized first, and cal_Chemistry)/Electrochemistry/Basics_of_Electrochemistry, Kahn Academy.
