Answered by DrBob222
An oxidizing agent must be reduced and that means a gain of electrons. So it must go from whatever oxidation state is shown to a lower positive value; i.e., it must gain electrons. For example, MnO4^- is +7 for Mn and it goes to +2, a decrease in positive value (a gain of 5 electrons) and that makes it reduced. Do the others the same way.
