PbO2 (s) + KNO2 (aq) + 2 HCl (aq) → PbCl2 (s) + KNO3 (aq) + H2O (l)
This is an oxidation-reduction (redox) reaction:
PbIV + 2 e- → PbII (reduction)
NIII - 2 e- → NV (oxidation)
PbO2 is an oxidizing agent, KNO2 is a reducing agent.
Reactants:
- PbO2 – Lead(IV) oxide
- KNO2
- 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.]
