Lead(II) iodide (or lead iodide) is a chemical compound with the formula PbI 2.At room temperature, it is a bright yellow odorless crystalline solid, that becomes orange and red when heated. [11]
Lead(II) nitrate is an inorganic compound with the chemical formula Pb(NO 3) 2.It commonly occurs as a colourless crystal or white powder and, unlike most other lead(II) salts, is soluble in water.
Lead(II) phosphate is an ionic compound with chemical formula Pb 3 (P O 4) 2.Lead(II) phosphate is a long-lived electronically neutral reagent chemical. [2] Despite limited tests on humans, it has been identified as a carcinogen based on tests on animals conducted by the EPA. [3]
There are three oxides known: PbO, Pb 3 O 4 (sometimes called "minium"), and PbO 2.The former has two allotropes: α-PbO and β-PbO, both with layer structure and tetracoordinated lead.

It is typically prepared from treating solutions of lead salts (e.g., (lead(II) nitrate) with bromide salts.This process exploits its low solubility in water - only 0.455 g dissolves in 100 g of water at 0 °C.
Lead(II) acetate is a white crystalline chemical compound with a slightly sweet taste.Its chemical formula is usually expressed as Pb(CH 3 COO) 2 or Pb(OAc) 2, where Ac represents the acetyl group.
In aqueous solution, lead(II) hydroxide is a somewhat weak base, forming lead(II) ion, Pb 2+, under weakly acidic conditions. This cation hydrolyzes and, under progressively increasing alkaline conditions, it becomes somewhat weak acid, and it forms Pb(OH) +, Pb(OH) 2 (aqueous), Pb(OH) − 3, and other species, including several polynuclear species, e.g., Pb 4 (OH) 4+ 4, Pb 3 (OH) 2+ 4, Pb 6 O ...
