	Metal Conservation
		When iron is buried in an aerobic soil or exposed on the surface to the air, the ferrous ions initially formed in the corrosion process oxidize to ferric ions, resulting in layers of ferric oxide scale on the metal surface.
		The secondary stage, the oxidation of the ferrous ion compounds to a ferric state, is modified in anaerobic environments.
		The hydrogen sulfide reacts with the ferrous ion from the anodic areas to produce ferrous sulfide and ferrous hydroxide, two major corrosion compounds of iron associated with objects recovered from the sea (Leigh 1973:205).

		First, while aluminum oxide can reduce seriously high phosphate levels, it often leaves enough phosphate in the water for nuisance algae to remain a problem.
		Regardless of the explanation, a hobbyist using iron oxide based phosphate removers should be aware of the potential decline of pH and plan accordingly.
		In summary, iron oxide based phosphate removers are effective at lowering phosphate levels in a reef tank and can reduce them to natural seawater levels.

	Rust Reduction via Electrolysis
		Since red rust (ferrous oxide) formation is an electrochemical process (oxidation), all we need to do is reverse this process.
		When ferric oxide oxidizes, ferrous oxide is formed (red rust).
		The beauty of this process is that the bond between the resulting clean metal and fl oxide is much weaker than the one between the metal and red rust.

	(18) Additional Challenges
		When magnesium is burned in air, some magnesium nitride is formed along with magnesium oxide.
		Magnesium oxide is 60.3% Mg and magnesium nitride is 72.2% Mg, so the percentage of magnesium is higher in magnesium nitride.
		From the previous question, the percentage of magnesium in magnesium nitride is higher than in magnesium oxide, therefore the percentage of the other element in magnesium nitride is less than in magnesium oxide, therefore the increase in mass will be less in forming magnesium nitride than in forming magnesium oxide.
