Lead dinitrate

Properties, data and information sources.

 

Contents

Lead nitrate is an inorganic compound chemically described as the salt of the divalent element lead and Nitric acid. Lead nitrate was first identified in 1597 by the alchemist Andreas Libavius, who called the substance plumbum dulce, which—referring to the substance´s taste—means sweet lead.

Data and Properties

In its pure form, lead(II) nitrate exists as a white powder or in the form of colorless cubic crystals that are easily soluble in water and taste sweet.

solubility:
+ Readily soluble in water (376.5 g/L at 0 °C; 522 g/L at 20 °C; 597 g/L at 25 °C; 1270 g/L at 100 °C).
- Hardly soluble in alcohol.
decomposition temperature
470 °C
density
4.53 g cm-1 at 20 °C

standard enthalpy of formation
-451.9 kJ/mol at 25 °C
magnetic susceptibility χ
-74 × 10-6 cm3 mol-1
crystal structure:
Lead nitrate crystallizes in the cubic system, space group Pa3, no. 205, where each face of the cube is 784 pm long. Previous research interest in the crystal structure of lead(II) nitrate was partly based on the possibility of free internal rotation of the nitrate groups within the crystal lattice at elevated temperatures, but this could not be observed [Heger et al. 1986].
