8 Li + 5 H2SO4 → 4 H2O + H2S + 4 Li2SO4
This is an oxidation-reduction (redox) reaction:
SVI + 8 e- → S-II (reduction)
8 Li0 - 8 e- → 8 LiI (oxidation)
H2SO4 is an oxidizing agent, Li is a reducing agent.
Reactants:
Products:
- H2O – Water, oxidane
- 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.]
- Li2SO4 – Lithium sulfate
