Question

what is the experiment, observation, inference and reaction when lead dioxide (PbO2) is heated?

​

Answer 1

Answer:

Lead (IV) oxide is thermally unstable and it tends to decompose into lead(II) oxide and oxygen upon heating. Whereas when lead(II) oxide is heated to around 450-480 °C, it forms lead(II,IV) oxide, also known as red lead or triplumbic tetroxide. If it is heated above 480 °C, reverse reaction will occur.
