2 HNO3 + 3 I2 + 2 H2O → 6 HIO + 2 NO
This is an oxidation-reduction (redox) reaction:
6 I0 - 6 e- → 6 II (oxidation)
2 NV + 6 e- → 2 NII (reduction)
I2 is a reducing agent, HNO3 is an oxidizing agent.
Reactants:
- 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.
