Lead Nitrate

Lead Nitrate

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.

Molecular Formula : Pb(NO3)2
Molecular Weight: 331.23

Lead Nitrate Specification:

Item Index
Assay (%) ≥98.0
Fe≤ ≤0.05
Cu (%) ≤ ≤0.05
Free Acid% ≤0.1
Water Insoluble% ≤0.05

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.

 

Numerous health conditions can affect the nerves that will lead to impotency. Many people agreed that over half of all men with erectile dysfunction are thought to have some physical cause. Viagra is a common remedy used to treat inability to get or keep an erection. If you are considering 10mg tadalafil, you probably wish to know about 5mg tadalafil.
