    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.
