2 KOH (aq) + 2 NO2 (l) → KNO2 (aq) + KNO3 (aq) + H2O (l)
This is an acid-base reaction (neutralization): KOH is a base, NO2 is an acid.
This is an oxidation-reduction (redox) reaction:
NIV - 1 e- → NV (oxidation)
NIV + e- → NIII (reduction)
NO2 is both an oxidizing and a reducing agent (disproportionation (dismutation)).
Reactants:
- KOH – Potassium 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.]
