Question

What do you observe when orange coloured Pb3O4 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.

Answer 2

Answer:

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.

Explanation:

If it is heated above 480 °C, reverse reaction will occur.

2Pb3O4→6PbO+O2
