Lead(II) sulfide is an inorganic compound with the formula PbS.
- 2 PbS + 3 O2 → 2 PbO + 2 SO2
- PbO + C → Pb + CO
- 2 PbO + C → 2 Pb + CO2
Lead(II) sulfide is a black solid, insoluble in all solvents.
PbS is a semiconductor and was one of the earliest materials to be used as a semiconductor.
Lead sulfide is sold by chemical suppliers.
Lead(II) sulfide occurs naturally as the mineral galena.
- Pb(CH3COO)2 + H2S → PbS↓ + 2 CH3COOH
- Mineral collecting
- Make lead metal (Dangerous!)
- Make infrared detector
- Make black pigment
Lead(II) sulfide is so insoluble that it is almost nontoxic, but pyrolysis of the material, as in smelting, gives dangerous lead oxide fumes.
In closed bottles. Galena crystals can be placed in a frame and placed in a place of choice.
Lead wastes should be taken to disposal centers.
