Lead bromide was prevalent in the environment as the result of the use of leaded gasoline. 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 ...
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) azide – Pb(N 3) 2; Lead(II) bromide – PbBr 2; Lead(II) carbonate – Pb(CO 3) Lead(II) chloride – PbCl 2; Lead(II) fluoride – PbF 2; Lead(II) hydroxide – Pb(OH) 2; Lead(II) iodide – PbI 2; Lead(II) nitrate – Pb(NO 3) 2; Lead(II) oxide – PbO; Lead(II) phosphate – Pb 3 (PO 4) 2; Lead(II) sulfate – Pb(SO 4) Lead(II ...
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
Pb and PbO would quickly over-accumulate and foul an engine. For this reason, 1,2-dichloroethane and 1,2-dibromoethane were also added to gasoline as lead scavengers—these agents form volatile lead(II) chloride and lead(II) bromide, respectively, which flush the lead from the engine and into the air: [15]
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.

Silver bromide (AgBr). Nearly all elements in the periodic table form binary bromides. The exceptions are decidedly in the minority and stem in each case from one of three causes: extreme inertness and reluctance to participate in chemical reactions (the noble gases, with the exception of xenon in the very unstable XeBr 2; extreme nuclear instability hampering chemical investigation before ...
