2 MnSO4 + 5 KBiO3 + 8 HNO3 → 2 KMnO4 + 5 BiONO3 + 3 KNO3 + 2 H2SO4 + 2 H2O
This is an oxidation-reduction (redox) reaction:
2 MnII - 10 e- → 2 MnVII (oxidation)
5 BiV + 10 e- → 5 BiIII (reduction)
MnSO4 is a reducing agent, KBiO3 is an oxidizing agent.
Reactants:
- MnSO4 – Manganese(II) sulfate
- KBiO3
- 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.]
