Insoluble in water. Slightly soluble in carbon dioxide solution, acetic acid and dilute nitric acid. Incompatible with strong acids and strong oxidizing agents.
CAS #: 7789-29-7
Forms colorless orthorhombic crystals; moh’s hardness 3-3.5; density 6.60 g/cm3. Decomposes on heating to give lead(II) carbonate, PbCO3, and hydrocerussite, Pb(CO3)2(OH). Soluble in acids and alkalies; insoluble in cold water, but transforms into the basic carbonate, 2PbCO3*Pb(OH)2, in hot water. Stable.
The most common source of human exposure to lead carbonate is inhalation of ambient air, but it can also be ingested orally and absorbed through the skin. It is released into the environment during mining and processing cerrusite ore (which is not commonly mined in the USA because most of the USA lead ore is galena, PbS). Runoff water containing this compound may result from sprays used to control dust in mining operations, and it can be found in the exhaust of cars that use leaded gasoline(1).
Laboratory animals exposed to this substance experience low to moderate systemic effects upon ingestion. The effects include gastrointestinal contractions, jaundice, convulsions, vomiting and degenerative changes in the brain (1).
Inhalation of large quantities of this compound can cause pulmonary edema and narcophobia. Chronic inhalation can produce a numbness, tingling and pain in the feet and hands, as well as hearing loss. It can also damage the liver and kidneys. The Thermo Scientific Chemicals product formerly known as Alfa Aesar ® is not available for purchase from us at this time.
