Pb(2) carbonate is the chemical compound with the chemical formula PbCOthree . It is a white solid with several practical uses, despite its toxicity.[2] Information technology occurs naturally as the mineral cerussite.[iii]
Structure [edit]
Like all metal carbonates, lead(II) carbonate adopts a dense, highly crosslinked construction consisting of intact CO 2− three and metal cation sites. As verified by X-ray crystallography, the Pb(II) centers are seven-coordinate, being surrounded by multiple carbonate ligands. The carbonate centers are bonded to bidentate to a single Lead and bridge to five other Pb sites.[four]
Pb site in
PbCO3 , highlighting 7-coordination and the presence of one bidentate carbonate ligand for each Lead centre.
Production and apply [edit]
Lead carbonate is manufactured past passing carbon dioxide into a common cold dilute solution of lead(Ii) acetate, or past shaking a suspension of a lead salt more soluble than the carbonate with ammonium carbonate at a low temperature to avoid germination of basic lead carbonate.[ii]
- Pb(CHiiiCOO)2 + [NHiv]2COthree → PbCO3 + 2 [NHiv](CH3COO)
Lead carbonate is used as a catalyst to polymerize formaldehyde to poly(oxymethylene). It improves the bonding of chloroprene to wire.[two]
Regulations [edit]
The supply and use of this compound is restricted in Europe.[5]
Other lead carbonates [edit]
A number of lead carbonates are known:
- White lead, a basic lead carbonate, 2PbCOthree·Pb(OH)2
- Shannonite, PbCO3·PbO
- Plumbonacrite, 3PbCO3·Pb(OH)ii·PbO [half dozen]
- PbCOthree·2PbO
- Abellaite, NaPb2(OH)(CO3)2
- Leadhillite, 2PbCOthree·PbSOiv·Pb(OH)ii
