Physical properties

TemperaturePressureDensity

Appearance: Lead nitrate is a white crystalline solid. The material is soluble in water. It is noncombustible but it will accelerate the burning of combustible materials. If large quantities of the material are involved in the fire an explosion may result. Prolonged exposure of the material to fire or heat may result in an explosion. Toxic oxides of nitrogen are produced in fires involving this material.[1]

Isotope pattern

Each peak is a nominal mass with its abundance-weighted exact mass, as a percentage of the tallest, from IUPAC natural isotope abundances.

Computed from the structure with RDKit 2026.09 when this page was built, beside PubChem's own computed values from its record; where the two differ, both are shown.

Predicted

log P: -0.86 Crippen (Wildman and Crippen 1999)
log S (water solubility): -1.35 ESOL (Delaney 2004), log mol/L
Synthetic accessibility: 3.05 SA score, 1 easy to 10 hard (Ertl and Schuffenhauer 2009)

Drug-likeness: Lipinski’s rule of five

Molecular weight ≤ 500: 331.21
log P ≤ 5 (Crippen): -0.86
H-bond donors ≤ 5: 0
H-bond acceptors ≤ 10: 6

Passes all four rules.

First aid

Remove at once all cases of lead intoxication from further exposure until the blood level is reduced to a safe value; immediately place the individual under medical care. Ingestion: Give gastric lavage using 1% solution of sodium or magnesium sulfate; leave 15-30 gm magnesium sulfate in 6-8 oz. Of water in the stomach as antidote and cathartic; egg white, milk, and tannin are useful demulcents; atropine sulfate and other antispasmodics may relieve abdominal pain, but morphine may be necessary. EYES or skin: Flush with water. (USCG, 1999)[1]
General First Aid: · Call 911 or emergency medical service. · Ensure that medical personnel are aware of the material(s) involved, take precautions to protect themselves and avoid contamination. · Move victim to fresh air if it can be done safely. · Administer oxygen if breathing is difficult. · If victim is not breathing: -- DO NOT perform mouth-to-mouth resuscitation; the victim may have ingested or inhaled the substance. -- If equipped and pulse detected, wash face and mouth, then give artificial respiration using a proper respiratory medical device (bag-valve mask, pocket mask equipped…[7]
Fresh air, rest. Refer for medical attention.[3]
Remove contaminated clothes. Rinse skin with plenty of water or shower.[3]

Storage

Separated from combustible substances, reducing agents and food and feedstuffs.[3]
Stow away from foodstuffs.[4]
Storage temp: Ambient. Venting: Open.[4]

Incompatibilities

Ignites or explodes when in presence of organic or easily oxidizable cmpd.[4]
Many metal oxo-compounds (nitrates, oxides, and particularly sulfates) and sulfides are reduced violently or explosively (ie undergo "thermite" reaction) on heating an intimate mixture with aluminium powder to a suitably high temperature. Contact of massive aluminium with molten salts may give explosions. (metal oxo-cmpd)[4]
Contact with red hot carbon causes an explosion with showers of sparks. If lead nitrate is used ... As the source of divalent lead, the crude dicyclopentadienyllead may explode violently during purification by high-vacuum sublimation at 100-130 °C. A heated mixture of (lead nitrate) and (potassium acetate) exploded violently.[4]
Reacts violently with ammonium thiocyanate; carbon; lead hypophosphite.[4]
