Tetraethyl lead was once widely used to improve the combustion properties of gasoline. To prevent the resulting lead oxides from fouling the engine, gasoline was treated with 1,2-Dibromoethane, which converted lead oxides into the more volatile lead bromide, which was then exhausted from the engine into the environment.

Among the halides, the iodide is less soluble than the bromide, which, in turn, is less soluble than the chloride. [3] Lead(II) oxide is also soluble in alkali hydroxide solutions to form the corresponding plumbite salt. [2] PbO + 2 OH − + H 2 O → Pb(OH) 2− 4. Chlorination of plumbite solutions causes the formation of lead's +4 oxidation ...
Lead(II) bromide – PbBr 2 [176] Lithium bromide – LiBr [177] ... Sodium chloride (table salt, rock salt) – NaCl; Sodium chlorite – NaClO 2; Sodium ...
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
The classic case is sodium bromide, which fully dissociates in water: NaBr → Na + + Br −. Hydrogen bromide, which is a diatomic molecule, takes on salt-like properties upon contact with water to give an ionic solution called hydrobromic acid. The process is often described simplistically as involving formation of the hydronium salt of bromide:
Many lead(II) pseudohalides are known, such as the cyanide, cyanate, and thiocyanate. [70] [74] Lead(II) forms an extensive variety of halide coordination complexes, such as [PbCl 4] 2−, [PbCl 6] 4−, and the [Pb 2 Cl 9] n 5n− chain anion. [73] Lead(II) sulfate is insoluble in water, like the sulfates of other heavy divalent cations.
Lead(II) sulfate (PbSO 4) is a white solid, which appears white in microcrystalline form.It is also known as fast white, milk white, sulfuric acid lead salt or anglesite.. It is often seen in the plates/electrodes of car batteries, as it is formed when the battery is discharged (when the battery is recharged, then the lead sulfate is transformed back to metallic lead and sulfuric acid on the ...
cobalt(II) nitrate hexahydrate Co(NO 3) 2 ·6H 2 O is made red by the chromophore of hydrated cobalt(II) [Co(H 2 O) 6] 2+. copper(II) sulfate pentahydrate CuSO 4 ·5H 2 O is made blue by the hydrated copper(II) cation. potassium permanganate KMnO 4 is made violet by the permanganate anion MnO − 4.
