3 Sb + 5 HNO3 + 2 H2O → 3 H3SbO4 + 5 NO
This is an oxidation-reduction (redox) reaction:
5 NV + 15 e- → 5 NII (reduction)
3 Sb0 - 15 e- → 3 SbV (oxidation)
HNO3 is an oxidizing agent, Sb is a reducing agent.
Reactants:
- Sb
- 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.
