[The Tao]

Hello,

I'm trying to make iron oxide, through electrolysis, but I don't have any pure iron. I was wondering if steel could be used, or would this complicate the reaction?

[AWK]

Which iron oxide?
I think a chemical method with heating is much better

[The Tao]

Actually, I don't know...I realize there are like 16 iron oxides, but I don't know which one is created through the process of electroylsis....the end result was a brown powder, it kind of looks like pigment...

[constant thinker]

I would have to guess it was probably iron (III) oxide, Fe₂O₃ (normal "rust"). The iron is oxidized to Fe⁺³.

Iron (II) oxide, FeO, is black if I remember correctly.

Could you supply a picture?

[The Tao]

I'ts not the black iron oxide, I think you're right too. It's the Iron (III) Oxide.

[enahs]

Yes, please do not make Ferrous oxide (FeO), the black colored powder. It is easily ignited and can cause explosions.


I will tell you a very easy way to make Rust, Iron(III) oxide, but first you must listen to my safety warnings.
It will result in the production of chlorine gas, which is highly toxic and can even kill you.
Only do it outside (or if you have access to a fume hood), where there is good ventilation (not under a porch roof). Wear a mask or filter if possible, and hold your breathe when you mix the reactants. Immediately step at least 6 feet away after mixing, and do not approach for at least 2 min after the reaction appears complete.

The reaction quite fun to watch.

Put a piece of steel wool in a dish of vinegar (just enough to submerge it), then add a few mL of bleach. Step back and follow the safety instructions.


Now, after you have done this experiment, look up what vinegar and bleach is (if you do not already know) and try and devise the chemical reaction or reactions?! taking place.

[The Tao]

Yes I already know that reaction. I don't necessarily have to make the black Iron Oxide...as other forms of Iron Oxide make thermite
