4 FeCr2O7 + O2 + 8 NaCO3 → 8 NaCrO4 + 2 Fe2O3 + 8 CO2
This is an oxidation-reduction (redox) reaction:
8 CV + 8 e- → 8 CIV (reduction)
4 FeII - 4 e- → 4 FeIII (oxidation)
8 CrVI - 8 e- → 8 CrVII (oxidation)
2 O0 + 4 e- → 2 O-II (reduction)
NaCO3 is an oxidizing agent, FeCr2O7 is a reducing agent, FeCr2O7 is a reducing agent, O2 is an oxidizing agent.
