PbCl 2 is used in synthesis of lead(IV) chloride (PbCl 4): Cl 2 is bubbled through a saturated solution of PbCl 2 in aqueous NH 4 Cl forming [NH 4] 2 [PbCl 6]. The latter is reacted with cold concentrated sulfuric acid (H 2 SO 4) forming PbCl 4 as an oil. [10] Lead(II) chloride is the main precursor for organometallic derivatives of lead, such ...
Lead(II) sulfate is poorly soluble, as can be seen in the following diagram showing addition of SO 2− 4 to a solution containing 0.1 M of Pb 2+. The pH of the solution is 4.5, as above that, Pb 2+ concentration can never reach 0.1 M due to the formation of Pb(OH) 2. Observe that Pb 2+ solubility drops 10,000 fold as SO 2− 4 reaches 0.1 M.

Lead chloride may refer to: Lead(II) chloride (plumbous chloride), mineral name: cotunnite. Lead(IV) chloride (plumbic chloride) Hexachloroplumbate(IV) (dianion)
ch 3 oc 6 h 5 + pb(oac) 4 → ch 3 oc 6 h 4 pb(oac) 3 + hoac The reaction is accelerated in the presence of dichloroacetic acid , which forms the lead(IV) dichloroacetate as an intermediate. Other organolead compounds are the halides of the type R n PbX (4-n) , sulfinates (R n Pb(OSOR) (4−n) ) and hydroxides (R n Pb(OH) (4−n) ).
"If one particular food has a small amount of heavy metals, eating a lot of that one food can give you a lot of that metal." This article was originally published on Feb. 1, 2023 and has been updated.
It is then converted to the ammonium salt (NH 4) 2 PbCl 6 by adding ammonium chloride (NH 4 Cl). Finally, the solution is treated with concentrated sulfuric acid H 2 SO 4, to separate out lead tetrachloride. This series of reactions is conducted at 0 °C. The following equations illustrate the reaction: PbCl 2 + 2HCl + Cl 2 → H 2 PbCl 6 H 2 ...
