2 MnSO4 + K2SO4 + 5 HNO3 + 3 H2O → 2 KMnO4 + 5 HNO2 + 3 H2SO4
This is an oxidation-reduction (redox) reaction:
2 MnII - 10 e- → 2 MnVII (oxidation)
5 NV + 10 e- → 5 NIII (reduction)
MnSO4 is a reducing agent, HNO3 is an oxidizing agent.
Reactants:
- MnSO4 – Manganese(II) sulfate
- K2SO4
- 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.]
- H2O – Water, oxidane
