Therefore, we chose those colors to represent SAAC. However, each type of cancer has its own color, and these are listed below:
Reaction of iron with the halogens. Iron reacts with excess of the halogens F2, Cl2, and Br2, to form ferric, that is, Fe(III), halides. This reaction is not very successful for iodine because of thermodynamic problems. The iron(III) is too oxidizing and the iodide is too reducing.
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.
