Thermal Decomposition of Lead(IV) Oxide

2PbO2 → 2PbO + O2

Ikhtisar

Lead(IV) oxide (lead dioxide) decomposes when heated above 290 C to form lead(II) oxide and oxygen. This decomposition reflects the instability of the +4 oxidation state for lead. Lead dioxide is a strong oxidizer used in lead-acid batteries.
