This is possible because two of the irons are +3, but the other one is +2. Should I call the police on then? Nov 29,2020 - Oxidation state of Fe in Fe3O4 ? Join Yahoo Answers and get 100 points today. The oxidation stateof Fe in Fe3O4 is 8/3. The key is that Fe can exist as Fe 2+ and Fe 3+ and in Fe2O4 both are present, there are in fact two Fe 3+ and one Fe 2+ making a total of eight positive charges to balance the eight negative charges. I am 100% certain that my answer is correct. When the Fe 2+ /Fe 3+ ratio increased from 1:2 to 3:1, the catalytic oxidation efficiency for 4-CP was slightly enhanced from 92% to 96% Is it in a problem with an equation? =), For the best answers, search on this site https://shorturl.im/awT6r. It's a trick question. The experimentally known highest oxidation state of iron has been determined to be Fe(vi) so far. A little unusual, but correct nonetheless. Still have questions? 3 + 3 + 2 = 8 A complex molecule with a transition metal does not need to have all the ions of the same metal be in the same oxidation state.
