Editing Lead(II) oxide (section)

==Reactions==
PbO is reduced to elemental lead when heated under [[carbon monoxide]] at around {{convert|1200|C|F|-2}}:
:PbO + CO → Pb + {{CO2}}

The red and yellow forms of this material are related by a small change in [[enthalpy]]:
:PbO<sub>(red)</sub> → PbO<sub>(yellow)</sub> {{pad|5em}} Δ''H'' = 1.6&nbsp;kJ/mol

PbO is [[amphoterism|amphoteric]], which means that it reacts with both acids and with bases. With acids, it forms salts of {{chem|Pb|2+}} via the intermediacy of oxo [[cluster chemistry|cluster]]s such as {{chem|[Pb|6|O(OH)|6|]|4+}}. With strong bases, PbO dissolves to form [[plumbite]] (also called plumbate(II)) salts:<ref name="Holl">{{Holleman&Wiberg}}{{page needed|date=June 2017}}</ref>
:PbO + {{H2O}} + {{chem|OH|−}} → {{chem|[Pb(OH)|3|]|−}}
