Lead(II) iodide (or lead iodide) is a chemical compound with the formula PbI 2 . At room temperature , it is a bright yellow odorless crystalline solid, that becomes orange and red when heated. [ 11 ]
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 ...
The low solubility of silver iodide and lead iodide reflects the covalent character of these metal iodides. A test for the presence of iodide ions is the formation of yellow precipitates of these compounds upon treatment of a solution of silver nitrate or lead(II) nitrate. [2] Aqueous solutions of iodide salts dissolve iodine better than pure ...
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.
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) 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 ...
A new review reports that nine people taking semaglutide and tirzepatide — the active ingredient in GLP-1 medications — experienced vision issues, including three potentially blinding eye ...
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
