Heating lead carbonate
Heating lead carbonate with hydrogen fluoride yields the hydrofluoride, which decomposes to the difluoride when it melts. This white crystalline powder is more soluble than the diiodide, but less than the dibromide and the dichloride. No coordinated lead fluorides exist (except the unstable PbF cation). The tetrafluoride, a yellow crystalline powder, is unstable. Lead carbonate is manufactured by passing carbon dioxide into a cold dilute solution of lead(II) acetate, or by shaking a suspension of a lead salt more soluble than the carbonate with ammonium carbonate at a low temperature to avoid formation of basic lead carbonate. Pb(CH3COO)2 + [NH4]2CO3 → PbCO3 + 2 [NH4](CH3COO) Lead carbonate is used as a catalyst to polymerize formaldehyde to poly(oxymethylene). It impr…

Web21 de dic. de 2024 · Lead carbonate forms colorless orthorhombic crystals; it decomposes at about 315 °C. It is nearly insoluble in cold water (0.00011 g/100 mL at 20 °C), but is transformed in hot water to the basic carbonate, 2PbCO3·Pb (OH)2. Lead carbonate is soluble in acids and alkalies, but insoluble in alcohol and ammonia. Web15 de dic. de 2024 · As well known, when heating lead carbonate a weight loss step due to dehydration reaction (100−200 °C) and the release of CO 2 (80−280 °C) are observed, which produce intermediate products (e.g. PbCO 3 ·PbO, 4PbCO 3 ·3PbO and PbCO 3 ·2PbO) and eventually, at 300−350 °C, when CO 2 is completely eliminated, PbO in form …
