Annealing of Silver Oxide
Blackish brown silver oxide is heated by a burner.
The oxygen that forms can be demonstrated with a glowing splint. White shiny silver metal remains in the test tube.
The thermal decomposition of silver oxide can be described by:
The decomposition does not take place at room temperature because there exists no potential drop.
However, since a gas, that means a substance with strongly negative temperature coefficient α, should be formed we expect that this process will begin at a high enough temperature.
