FeO3*3H2O + 3 H2S → FeS2 + S + 6 H2O
This is an oxidation-reduction (redox) reaction:
S-II - 2 e- → S0 (oxidation)
2 S-II - 2 e- → 2 S-I (oxidation)
FeVI + 4 e- → FeII (reduction)
H2S is a reducing agent, H2S is a reducing agent, FeO3*3H2O is an oxidizing agent.
Reactants:
- FeO3*3H2O
- 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.]
