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. The Pb–Cl covalent bonds have been measured to be 247 pm and the bond energy is 243 kJ⋅mol −1. [4]
Tarnished lead (left) and shiny lead (right) Compounds of lead exist with lead in two main oxidation states: +2 and +4. The former is more common. Inorganic lead(IV) compounds are typically strong oxidants or exist only in highly acidic solutions. [1] Red α-PbO and yellow β-PbO The mixed valence oxide Pb 3 O 4 Black PbO 2 which is a strong ...
Lead sesquioxide, Pb 2 O 3, which is a lead (II,IV) oxide as well (lead(II) metaplumbate(IV) [Pb 2+][PbO 2− 3]), reddish yellow Pb 12 O 19 , monoclinic, dark-brown or black crystals The so-called black lead oxide , which is a mixture of PbO and fine-powdered Pb metal and used in the production of lead–acid batteries .
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 compounds are those chemical compounds which contain lead. For lead compounds in the context of pharmacology and drug discovery , see lead compound . Subcategories
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Lead(IV) sulfide is a chemical compound with the formula Pb S 2. This material is generated by the reaction of the more common lead(II) sulfide , PbS, with sulfur at >600 °C and at high pressures. PbS 2 , like the related tin(IV) sulfide SnS 2 , crystallises in the cadmium iodide motif, which indicates that Pb should be assigned the formal ...
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
