In a recent class discussion, we addressed the following painting. Students had some great things to say, as usual. It was painted by _____________________ and conveys sentiments _________________ in America in the artists’ time.

4 OH-” is shown above the steel pipe, indicating the reaction at the steel surface. Below the magnesium rod, the chemical equation “Mg -> Mg2+ + 2e-” represents the anodic reaction that occurs at the magnesium rod. The background of the image is a gradient from white on the left to a light gray on the right.” width=”512″ height=”236″ loading=”lazy” data-api-endpoint=”https://asuce.instructure.com/api/v1/courses/9094/files/3267547″ data-api-returntype=”File”> Steel undergoes corrosion in the presence of water and oxygen. If a steel pipe is buried beneath the ground, see the diagram above, it can be protected from corrosion by using a magnesium metal rod driven into the ground close by. If the magnesium rod and the steel pipe are connected by a wire, then a voltaic cell is setup where electrons flow from the magnesium rod towards the steel pipe. The excess electrons at the pipe protect it from corrosion and are used to convert oxygen gas, O2, and water, H2O, into hydroxide ions, -OH (half reaction: O2 + H2O + 4e- → 4OH-). The reaction that occurs at the magnesium is shown in ethanol diagram above as a half reaction (Mg → Mg2+ + 2e-).   When the magnesium protects the steel pipe this way, is it undergoing oxidation or reduction?
