Explanation The rust can be prevented by placing a sacrificial electrode in electrical contact with the iron. The sacrificial electrode must be composed of a metal that oxidizes more easily than iron. The sacrificial electrode then oxidizes in place of the iron, protecting the iron from oxidation. From the given metals, Z n ( – 0

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 electrochemi…
