Which one of the following statements about the electrochemical reaction of dichromate and ferrous ions: Cr2022-(aq) + 14H+(aq) + 6Fe2+(aq) -> 2Cr3+(aq) + 6Fe3+ (aq) + 7H2O(1) > is FALSE? Cr atoms are reduced. Fe atoms are oxidized. The oxidation number of Cr changes from +6 to +3. The cell notation is Pt | Fe2+(aq), Fe3+(aq) || Cr2O72-(aq), Cr3+(aq), H+(aq), H2O(1) | Pt. The half-reaction occurring at the cathode is 6Fe2+(aq) -> 6Fe3+(aq) + 6e". ->
