For no real reason other than wanting to try an interesting electrolysis experiment, we try turning a piece of iron into iron oxide. This is done by using metallic iron as an anode in an electrolytic cell, producing iron hydroxide, which can be dehydrated to form high-quality iron oxide.
I really don't have a reason for doing this, and I'm not really interested in thermite or iron chemistry at this stage, but it was a fun and easy process nonetheless.
