What is the old name for FeO?
Either iron(II) oxide (old term ferrous oxide, chemical formula FeO) or iron(III) oxide (old term ferric oxide, chemical formula Fe2O3).
Why is FeO called iron II?
This is where the Roman numeral II comes from after iron’s symbol. This means each iron atom turns into the ion Fe+2 and each oxygen atom turns into the oxide ion O-2. Since these ions are oppositely charged they attract each other giving us the formula FeO. The black rocks and dirt on Mars are iron(II) oxide.
Where can I find FeO?
The most efficient method is to use Mossbauer spectroscopy which can directly analyse and distinguish Fe2+ and Fe3+. To get FeO to Fe2O3 just multiply FeO by 1.11111 Fe2O3 to FeO is just reverse, divide Fe2O3 by 1.11111 (or multiply by 0.89998).
