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.
This page provides supplementary chemical data on lead(II) chloride. Structure and properties. Molecular structure Point group? Coordination geometry?
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 chloride may refer to: Lead(II) chloride (plumbous chloride), mineral name: cotunnite. Lead(IV) chloride (plumbic chloride) Hexachloroplumbate(IV) (dianion)
On Monday, the U.S. Food and Drug Administration (FDA) announced that, for the first time, it is setting guidelines for an acceptable level of lead in processed baby food, including canned fruit ...
The Food and Drug Administration has issued an alert for elevated lead levels in ground cinnamon products sold at discount stores such as Dollar Tree, Family Dollar and Save A Lot.. The FDA says ...
It is believed to be one of the main sources of high lead levels in the country. [291] In Hong Kong the maximum allowed lead level in food is 6 parts per million in solids and 1 part per million in liquids. [292] Lead-containing dust can settle on drying cocoa beans when they are set outside near polluting industrial plants. [293]
