Lead nitrate is an oxidizer and has been used as such in [[pyrotechnics]].<ref name="pyrotechnica"/> It is soluble in water and dilute nitric acid.

[[Alkali salt|Basic nitrates]] are formed when alkali is added to a solution. {{chem2|Pb2(OH)2(NO3)2}} is the predominant species formed at low [[pH]]. At higher pH {{chem2|Pb6(OH)5NO3}} is formed.<ref name="pauley">{{cite journal|title = Basic Salts of Lead Nitrate Formed in Aqueous Media|first = J. L.|last = Pauley|author2=M. K.

There is no evidence for the formation of the hydroxide, {{chem2|Pb(OH)2}}, in aqueous solution below pH 12.

Solutions of lead nitrate can be used to form co-ordination complexes. Lead(II) is a [[HSAB theory|hard acceptor]]; it forms stronger complexes with [[nitrogen]] and [[oxygen]] electron-donating ligands. For example, combining lead nitrate and [[polyethylene glycol|pentaethylene glycol]] (shortened to EO5 in the referenced paper) in a solution of [[acetonitrile]] and [[methanol]] followed by slow evaporation produced the compound [{{chem2|Pb(NO3)2}}EO5].<ref>{{cite journal|title = Structural Chemistry of Poly (ethylene glycol).

The two bidentate nitrate [[ligand]]s are in [[Cis-trans isomerism|trans configuration]]. The total [[coordination number]] is 10, with the lead ion in a bicapped [[square antiprism]] [[molecular geometry]].

The complex formed by lead nitrate with a [[bithiazole]] bidentate N-donor ligand is binuclear. The crystal structure shows that the nitrate group forms a bridge between two lead atoms.<ref name=mahjoub>{{cite journal|title = A Dimeric Mixed-Anions Lead(II) Complex: Synthesis and Structural Characterization of [Pb<sub>2</sub>(BTZ)<sub>4</sub>(NO<sub>3</sub>)(H<sub>2</sub>O)](ClO<sub>4</sub>)<sub>3</sub> {BTZ = 4,4'-Bithiazole}|first = Ali Reza|last = Mahjoub|author2 = Ali Morsali|journal = [[Chemistry Letters]]|volume = 30|issue = 12|year = 2001|page= 1234|doi=10.1246/cl.2001.1234}}</ref> One 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 [[lone pair]] of lead electrons, also found in lead complexes with an [[imidazole]] ligand.<ref name=wan>{{cite journal|title = 2D 4.8<sup>2</sup> Network with threefold parallel interpenetration from nanometre-sized tripodal ligand and lead(II) nitrate|author = Shuang-Yi Wan|author2 =  Jian Fan|author3 = Taka-aki Okamura|author4 = Hui-Fang Zhu|author5 = Xing-Mei Ouyang|author6 = Wei-Yin Sun|author7 = Norikazu Ueyama|name-list-style = amp|journal = [[Chemical Communications|Chem.
