4 Cu(NO3)2*3H2O → 2 Cu2O + 8 NO2 + 3 O2 + 12 H2O
This is an oxidation-reduction (redox) reaction:
4 CuII + 4 e- → 4 CuI (reduction)
8 NV + 8 e- → 8 NIV (reduction)
6 O-II - 12 e- → 6 O0 (oxidation)
Reactants:
- Cu(NO3)2*3H2O
Products:
- Cu2O – Copper(I) oxide
- 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.]
- O2
- H2O – Water, oxidane
