3 Ag3CuS2 + 32 HNO3 → 9 AgNO3 + 3 Cu(NO3)2 + 17 NO + 6 H2SO4 + 10 H2O
This is an oxidation-reduction (redox) reaction:
3 CuI - 3 e- → 3 CuII (oxidation)
6 S-II - 48 e- → 6 SVI (oxidation)
17 NV + 51 e- → 17 NII (reduction)
Ag3CuS2 is a reducing agent, Ag3CuS2 is a reducing agent, HNO3 is an oxidizing agent.
Reactants:
- Ag3CuS2
- 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.
