6 CuI (s) + 16 HNO3 (aq) → 6 Cu(NO3)2 (aq) + 3 I2 (s) + 4 NO (g) + 8 H2O (l)
This is an oxidation-reduction (redox) reaction:
6 CuI - 6 e- → 6 CuII (oxidation)
6 I-I - 6 e- → 6 I0 (oxidation)
4 NV + 12 e- → 4 NII (reduction)
CuI is a reducing agent, CuI is a reducing agent, HNO3 is an oxidizing agent.
Reactants:
- CuI – Copper(I) iodide
- 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.]
