2 Mn(NO3)2 + 5 Na3BiO4 + 26 HNO3 → 2 HMnO4 + 5 Bi(NO3)3 + 15 NaNO3 + 12 H2O
This is an oxidation-reduction (redox) reaction:
2 MnII - 10 e- → 2 MnVII (oxidation)
5 BiV + 10 e- → 5 BiIII (reduction)
Mn(NO3)2 is a reducing agent, Na3BiO4 is an oxidizing agent.
Reactants:
- Mn(NO3)2 – Manganese(II) nitrate
- Na3BiO4
- 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.]
