Because of this property, lead nitrate is sometimes used in pyrotechnics such as fireworks. Its decomposition can emit toxic nitric oxide gas. Discard the filtrate and put the precipitate and filter paper together back into the original beaker; add 30 mL acetic acid-sodium acetate buffer solution and boil until the lead sulfate is completely dissolved. It has large impact on protein metabolism, cell energy balance and the genetic system. They have been linked to renal cancer and glioma in experimental animals and to renal cancer, brain cancer and lung cancer in humans, although studies of workers exposed to lead are often complicated by concurrent exposure to arsenic. 91.6 g/60 C; 111 g/80 C; 133 g/100 C.

It is soluble in water, liquid ammonia, slightly soluble in ethanol but insoluble in concentrated nitric acid (generate protective film). (2) Calibration: Used under license. [12] One interesting aspect of this type of complexes is the presence of a physical gap in the coordination sphere, i.e., the ligands are not placed symmetrically around the metal ion. This is potentially due to a lead lone pair of electrons, also found in lead complexes with an imidazole ligand. Lead II Nitrate Formula Structure, //Lead(II) nitrate 99% | VWR //]]>. Excess acid prevents the formation of basic nitrates, and the desired lead nitrate can be crystallized by evaporation.

This is potentially due to a lead lone pair of electrons, also found in lead complexes with an imidazole ligand.[13]. Required fields are marked *. Lead nitrate, like other lead compounds, is highly toxic and is a cumulative poison that accumulates in the body. Thus lead nitrate is used as a flotation agent in titanium removal from clays; in electrolytic refining of lead; in rayon delustering; in red lead manufacture; in matches, pyrotechnics, and explosives; as a heat stabilizer in nylon; as a coating on paper for photothermography; as an esterification catalyst for polyesters; as a rodenticide; as an electroluminescent mixture with zinc sulfide; as a means of electrodepositing lead dioxide coatings on nickel anodes; and as a means of recovering precious metals from cyanide solutions. The precipitate is sucked dry on a sintered-glass funnel, then transferred to a crystallising dish which is covered by a clock glass and left in an electric oven at 110o for several hours [Beck et al. After the lead solution is added, slightly heat to maintain 10~15min, and then quickly filter, otherwise it is difficult to achieve the desired results.

Contact with eyes causes irritation. The nuclear rupture may be due to that the lead nitrate destroy the nuclear pore complex protein. Our product offerings can help with biomedical research, forensic work, and clinical diagnostics. Lead nitrate is relatively unreactive and can be stored almost indefinitely, preferably in a labeled, difficult-to-open container to avoid accidental poisonings. The pH value of aqueous solution of crude lead nitrate is 1~2; use ammonia to adjust to until the turbid phenomenon doesnt disappear as more, the pH value at this time is 3~4. Browse Lead(II) nitrate and related products at MilliporeSigma. 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 did not materialise.[10].
