2 Fe(OH)2 + 8 NO2 → 2 Fe(NO3)3 + N2 + 2 H2O
This is an acid-base reaction (neutralization): Fe(OH)2 is a base, NO2 is an acid.
This is an oxidation-reduction (redox) reaction:
2 NIV + 8 e- → 2 N0 (reduction)
6 NIV - 6 e- → 6 NV (oxidation)
2 FeII - 2 e- → 2 FeIII (oxidation)
NO2 is an oxidizing agent, NO2 is a reducing agent, Fe(OH)2 is a reducing agent.
Reactants:
- Fe(OH)2 – Iron(II) hydroxide
- NO2 – Nitrogen dioxide
- Other names: Nitrogen(IV) oxide , Deutoxide of nitrogen , Nitrogen peroxide
- Appearance: Brown gas ; Reddish-brown gas or brown or yellow liquid with pungent odour ; Yellowish-brown liquid or reddish-brown gas (above 70°F) with a pungent, acrid odor. [Note: In solid form (below 15°F) it is found structurally as N2O4.]
