What Is Pb(CO3)2?

Pb(CO3)2 is the chemical formula of lead(IV) carbonate. Lead(IV) carbonate is also referred to as plumbic carbonate and is prepared industrially from lead(II) acetate and carbon dioxide. The substance appears naturally as the mineral cerussite.

Lead carbonate is created by passing carbon dioxide into a cold, dilute solution of lead(II) acetate. Shaking a suspension of a lead salt less soluble than the carbonate with ammonium carbonate also manufactures the substance, as long as the reaction takes place at a low temperature to prevent the formation of basic lead carbonate. This compound is restricted in the United States and Europe for health and safety reasons.
