2 NO (g) + H2O (l) + 3 HClO (aq) → 2 HNO3 (aq) + 3 HCl (aq)
This is an oxidation-reduction (redox) reaction:
3 ClI + 6 e- → 3 Cl-I (reduction)
2 NII - 6 e- → 2 NV (oxidation)
HClO is an oxidizing agent, NO is a reducing agent.
Reactants:
- NO – Nitrogen monoxide , Oxidonitrogen(•) (additive)
- H2O – Water, oxidane
- HClO – Hypochlorous acid, chloric(I) acid, chloranol, hydroxidochlorine
Products:
- HNO3 – Nitric acid
- Other names: Aqua fortis , Spirit of niter , Eau forte
- Appearance: Colorless, yellow or red fuming liquid ; Colourless-to-yellow liquid with pungent odour ; Colorless, yellow, or red, fuming liquid with an acrid, suffocating odor. [Note: Often used in an aqueous solution. Fuming nitric acid is concentrated nitric acid that contains dissolved nitrogen dioxide.]
- HCl – Chlorane , Hydrogen chloride
- Other names: Hydrochloric acid , M , Uriatic acid
- Appearance: Colorless, transparent liquid, fumes in air if concentrated ; Colorless gas ; Colourless compressed liquefied gas with pungent odour ; Colorless to slightly yellow gas with a pungent, irritating odor. [Note: Shipped as a liquefied compressed gas.]
