4 Al(NO3)3 (aq) → 3 O2 (g) + 12 NO2 (l) + 2 Al2O3 (s)
This is an oxidation-reduction (redox) reaction:
12 NV + 12 e- → 12 NIV (reduction)
6 O-II - 12 e- → 6 O0 (oxidation)
Al(NO3)3 is an oxidizing agent, Al(NO3)3 is a reducing agent.
This is a precipitation reaction: Al2O3 is the formed precipitate.
This is a gas evolution reaction, O2 is the formed gas.
- Al(NO3)3 – Aluminium nitrate
- 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.]
