Lead(II) chloride is a chemical compound with the chemical formula PbCl2.
Addition of chloride ions to a suspension of PbCl2 gives rise to soluble complex ions.
PbCl2 reacts with molten sodium nitrite to give PbO:
- PbCl2 + 3 NaNO2 → PbO + NaNO3 + 2 NO + 2 NaCl
If chlorine gas is bubbled through a saturated solution of PbCl2 with ammonium chloride, ammonium hexachloroplumbate [NH4]2[PbCl6] is obtained. If cold concentrated sulfuric acid is added to the solid compound, while maintaining the temperature around 0 °C, lead(IV) chloride (PbCl4) is obtained, as a clear oil.
Lead(II) chloride is the main precursor for organometallic derivatives of lead, such as plumbocenes.
Lead(II) chloride is a white solid, slightly soluble in water.
Lead(II) chloride is sold by chemical suppliers.
PbCl2 occurs naturally in the form of the mineral cotunnite.
Lead(II) chloride precipitates from solution upon addition of chloride sources (HCl, NaCl, KCl) to aqueous solutions of soluble lead(II) compounds:
- Pb(NO3)2 + 2 NaCl → PbCl2 + 2 NaNO3
- Pb(CH3COO)2 + HCl → PbCl2 + 2 CH3COOH
The addition of HCl to lead(II) carbonate will also produce lead(II) carbonate, although due to the low solubility of the lead chloride, this reaction is slow.
- PbCO3 + 2 HCl → PbCl2 + CO2 + H2O
- PbO2 + 4 HCl → PbCl2 + Cl2 + 2 H2O
- PbO + 2 HCl → PbCl2 + H2O
Chlorine gas will react with lead metal to form lead dichloride.
- Pb + Cl2 → PbCl2
- Make lead tetrachloride
- Make Pattinson's white lead
- Make plumbocenes
- Mineral collecting
Like other lead-containing compounds, PbCl2 is extremely toxic and any exposure of sufficient dose can lead to lead poisoning.
