Wyckoff [wyck-off] as a boys' name is of Old German origin, and the meaning of Wyckoff is wine seller.
Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe2O3. It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO), which is rare, and iron(II,III) oxide (Fe3O4), which also occurs naturally as the mineral magnetite. As the mineral known as hematite, Fe2O3 is the main source of iron for the steel industry. Fe2O3 is ferromagnetic, dark red, and readily attacked by acids. Iron(III) oxide is often called rust, and to some extent this label is useful, because rust shares several properties and has a similar composition.
Best Answer: Actually, the iron(III) ion, [Fe(H2O)6]3+, is an extremely pale purplish colour, as you will see if you grow a crystal of iron ammonium alum, NH4Fe(SO4)2.12H2O.This is because the ion is high spin d5, meaning that d-d transitions are spin-forbidden, and therefore even weaker than usual.ron(II) ion = green. Iron(III) ion = yellow. Rust (Iron oxide + water)= black or brown. Explain why the rust of iron is not green or yellow, but black or brown. Add your answer. Source.
