Question

Quizplus · Accepted Answer

Aluminum is resistant to corrosion primarily because its surface is coated with a thin, protective layer of aluminum oxide (Al2O3). This layer prevents further oxidation of the aluminum beneath it. The correct option, despite the encoding error, refers to aluminum oxide, not Al₂O₃. Aluminum is not a noble metal, does not have the greatest density among metals, and its corrosion resistance is not due to a high positive standard reduction potential.
