3 SnS2 + 16 HNO3 + H2O → 3 H2SnO3 + 16 NO + 6 H2SO4
This is an oxidation-reduction (redox) reaction:
6 S-II - 48 e- → 6 SVI (oxidation)
16 NV + 48 e- → 16 NII (reduction)
SnS2 is a reducing agent, HNO3 is an oxidizing agent.
Reactants:
- SnS2 – Tin(IV) sulfide
- 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
