The chemical compound Lead(II) nitrate is the inorganic salt of
nitric acid and Lead. It is a highly toxic and carcinogenic
colorless crystal or white powder and a strong, stable oxidizer.
Unlike many Lead(II) salts, it is soluble in water.

Characteristics
White crystals or crystalline, relative density 4.53(20),
Strongly oxidizing , poisonous , easily soluble in water and
alcohol, liquid ammonia, light dissolve in ethyl alcohol, not
dissolve in concentrated nitrate acid, solubility 56.5g/100g water
(20). Dry Lead nitrate decompose at 205-223. Damp Lead nitrate
decompose at 100, first become Pb(NO3)2 . PbO, go on heating, and
then become PbO. It is strong oxidant, putting together with
organics will Lead it burning, noxious
Applications
Lead nitrate is used in the manufacture of matches and special
explosives such as Lead azide, in mordants for dyeing and printing
calico textiles, in the manufacture of Lead compounds, as heat
stabilizer in nylon and polyesters, as coating of photothermograpic
paper, and rodenticides.
Is it reported that Lead nitrate has an effect on the leaching
process in gold cyanidation, improving speed and yield, particularly
in processing partially oxidized ores.
Lead Nitrate is used as medical astringent; tanning material for
leather-making, dyeing/textile mordant; paint pigment, photograph
promoting sensitizer/agent, flotation for ore, chemical reagents,
for making fireworks, match, explosives, tanning, engraving and
other Lead salts.
It is also used for match manufacturing and explosives, for
processing engraving and mordant in mother-of-pearl staining. It is
an oxidizer in the dye industry.
Safety
The Metal Lead and its unsoluble salt Lead sulfide are not
considered particularly dangerous. However, the soluble salts such
as Lead(II) chloride and very soluble Lead(II) nitrate may Lead to
Lead poisoning. Intoxication symptoms are intestinal malfunction,
strong abdominal pains, appetite loss, nausea, vomiting and cramps.
Due care should be taken before and during handling of the material.
