Stannous chloride (SnCl 2) is used for the same purpose. [15] Pb is used in HCl service even though the PbCl 2 formed is slightly soluble in HCl. Addition of 6–25% of antimony (Sb) increases corrosion resistance. [16] A basic chloride of lead, PbCl 2 ·Pb(OH) 2, is known as Pattinson's white lead and is used as pigment in white paint. [17]
Lead chloride may refer to: Lead(II) chloride (plumbous chloride), mineral name: cotunnite. Lead(IV) chloride (plumbic chloride) Hexachloroplumbate(IV) (dianion)
The chloride of this oxidation state is formed only with difficulty and decomposes readily into lead(II) chloride and chlorine gas. The bromide and iodide of lead(IV) are not known to exist. [3] Lead dioxide dissolves in alkali hydroxide solutions to form the corresponding plumbates. [2] PbO 2 + 2 OH − + 2 H 2 O → Pb(OH) 2− 6
Organolead compounds can be derived from Grignard reagents and lead chloride. For example, methylmagnesium chloride reacts with lead chloride to tetramethyllead, a water-clear liquid with boiling point 110 °C and density 1.995 g/cm 3. Reaction of a lead(II) source with sodium cyclopentadienide gives the lead metallocene, plumbocene.
Lead use was further curtailed by the European Union's 2003 Restriction of Hazardous Substances Directive. [317] A large drop in lead deposition occurred in the Netherlands after the 1993 national ban on use of lead shot for hunting and sport shooting: from 230 tonnes in 1990 to 47.5 tonnes in 1995. [318]
Lead tetrachloride, also known as lead(IV) chloride, has the molecular formula PbCl 4. It is a yellow, oily liquid which is stable below 0 °C, and decomposes at 50 °C. [ 2 ] It has a tetrahedral configuration , with lead as the central atom.

Lead halide refers to any of a group of chemical compounds in which lead is joined to an element from the halide group. Compounds within this group include: Lead(II) fluoride; Lead(II) chloride; Lead(II) bromide; Lead(II) iodide
