This page was last modified on 11 December 2019, at 00:10. When heated, lead(II) nitrate crystals decompose to lead(II) oxide, dioxygen and nitrogen dioxide, accompanied by a crackling noise. Nothing that happens in the labor other workplace is as important as your health and safety. Since Pb(NO3)2 has very low solubility in nitric acid, the lead(II) nitrate is crystallised directly from the solution. [9] It is soluble in water and dilute nitric acid. To improve the leaching process in the gold cyanidation, lead(II) nitrate solution is added. The crystal structure shows that the nitrate group forms a bridge between two lead atoms. Lead nitrate | Pb(NO3)2 - PubChem Since around the year 2000, lead(II) nitrate has begun to be used in gold cyanidation.
