    oxidation = redox. so I'd say: Fe3+ (aq) ----> Fe2+(aq)

    Loco, if you wouldn't mind posting these types of questions in the appropriate group (there is a Chemistry group on the home page). I know they aren't quite as busy as this group, but they'll never get there if there are no good questions :). You can always try to get some friends on chat to come over and help you.

    No wait, it's E. B is reduction, E is oxidation...
