6 Sb + 10 HNO3 → 3 Sb2O5 + 10 NO + 5 H2O
This is an oxidation-reduction (redox) reaction:
10 NV + 30 e- → 10 NII (reduction)
6 Sb0 - 30 e- → 6 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.
