The Oxidation of Aluminum – Corrosion Pro Articles

Jul 30, 2014 · Aluminum being the most abundant metal in the earth's crust (at 8.2% of the total metals) is never found free in nature. Aluminum is reactive and will react spontaneously with water and/or air to form aluminum oxide. Aluminum oxide, Al2O3, forms a stable passive layer that protects aluminum from corrosion or further oxidation.

Chemistry of Aluminum (Z=13) - Chemistry LibreTexts

Aluminum Compounds. Although it does not seem to be particularly reactive, aluminum is considered an active metal. Its behavior is deceptive because it reacts rapidly with the oxygen in the air to form aluminum oxide ((Al_2O_3)), or alumina, which is tightly bound to the metal and exists as a dense coating (unlike the oxides of iron). This coating protects it from further reaction.

Jul 19, 2010 · Let's look at cobalt (III) oxide. Cobalt (III) means its cobalt ion with valency of 3 and since metals form positive ions, this is Co3+ ion. Oxide ion = O2- Thus cobalt (III) oxide should have the chemical formula Co2O3 (swop the valencies to get the formula of the compound formed) Balanced chemical equation: 4Co + 3O2 --> 2Co2O3 Hope this helps.
