Feb 19, 2016 · But they still each have a negative 1 oxidation state. So the chlorine was neither oxidized nor reduced in this reaction. But this is definitely an oxidation-reduction reaction, or a redox reaction, because you had something getting oxidized and something being reduced. Iron was oxidized by the hydrogen, and the hydrogen was reduced by the iron.
