I recently successfully made thermite from iron oxide powder and aluminum powder. However, I have a couple of questions about copper and iron oxides.
The kind of iron oxide that is made by electrolyzing iron in a salt water bath. You rinse the solution well to get some of the salt out then boil off/dry the remaining sludge. What is left is a red powder. What kind of iron oxide is this? (II,III)
Lastly, if I repeated the same process with copper, would I get copper(I) oxide or copper(II) oxide?
Apologies for my lack of knowledge in chemistry.
