4 Ag + 2 H2S + O2 → 2 Ag2S + 2 H2O
This is an oxidation-reduction (redox) reaction:
4 Ag0 - 4 e- → 4 AgI (oxidation)
2 O0 + 4 e- → 2 O-II (reduction)
Ag is a reducing agent, O2 is an oxidizing agent.
Reactants:
- Ag
- H2S – Hydrogen sulfide
- Other names: D , Ihydrogen monosulfide|Dihydrogen sulfide|Sewer gas|Sulfane|Sulfurated hydrogen|Sulfureted hydrogen|Sulfuretted hydrogen|Sulfur hydride|Hydrosulfuric acid|Hydrothionic acid|Thiohydroxic acid|Sulfhydric acid}} , Hydrosulfuric acid
- Appearance: Colorless gas ; Colourless compressed liquefied gas with characteristic odour of rotten eggs ; Colorless gas with a strong odor of rotten eggs. [Note: Sense of smell becomes rapidly fatigued & can NOT be relied upon to warn of the continuous presence of H2S. Shipped as a liquefied compressed gas.]
- O2
