2 NaOH (aq) + NO2 (l) + NO (g) → 2 NaNO2 (aq) + H2O (l)
This is an acid-base reaction (neutralization): NaOH is a base, NO2 is an acid.
This is an oxidation-reduction (redox) reaction:
NII - 1 e- → NIII (oxidation)
NIV + e- → NIII (reduction)
NO is a reducing agent, NO2 is an oxidizing agent (synproportionation (comproportionation)).
- 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.]
- NO – Nitrogen monoxide , Oxidonitrogen(•) (additive)
- H2O – Water, oxidane
