5 PH3 (g) + 8 KMnO4 (aq) + 24 HCl (aq) → 5 H3PO4 (aq) + 8 KCl (aq) + 8 MnCl2 (aq) + 12 H2O (l)
This is an oxidation-reduction (redox) reaction:
5 P-III - 40 e- → 5 PV (oxidation)
8 MnVII + 40 e- → 8 MnII (reduction)
PH3 is a reducing agent, KMnO4 is an oxidizing agent.
Reactants:
- PH3 – Phosphane
- KMnO4 – Potassium manganate(VII)
- 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.]
