The compound lead(II) nitrate is the nitrate of lead with chemical formula Pb(NO3)2. It is also known as lead dinitrate, nitric acid lead(II) salt, and plumbous nitrate. 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.
When lead(II) nitrate is heated, it decomposes to lead(II) oxide , accompanied by a crackling noise referred to as "decrepitation". When lead(II) nitrate reacts with potassium iodide, the precipitate is a bright yellow substance, lead(II) iodide.
Pb(NO3)2(aq) + 2KI(aq) ---> PbI2(s) + 2 KNO3(aq)
