3 TeO2 + KMnO4 + 2 HNO3 + 8 H2O → 3 H6TeO6 + KNO3 + Mn(NO3)
This is an oxidation-reduction (redox) reaction:
3 TeIV - 6 e- → 3 TeVI (oxidation)
MnVII + 6 e- → MnI (reduction)
TeO2 is a reducing agent, KMnO4 is an oxidizing agent.
Reactants:
- TeO2
- KMnO4 – Potassium manganate(VII)
- 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
