8 H2O2 + 8 H2S → S8 + 16 H2O
This is an oxidation-reduction (redox) reaction:
8 S-II - 16 e- → 8 S0 (oxidation)
16 O-I + 16 e- → 16 O-II (reduction)
H2S is a reducing agent, H2O2 is an oxidizing agent.
Reactants:
- H2O2 – Hydrogen peroxide
- 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.]
