Some
binary compounds decompose to component elements (redox).
Nitrate, if it decomposes, either decompose to nitrite and oxygen or to
the oxide, nitrogen dioxide and oxygen (redox).
Carbonate,
if it decomposes, to oxide and carbon dioxide (not redox).
Sulfate, if it decomposes, either to sulfite and oxygen or to the
oxide, sulfur dioxide and oxygen (redox).
Chlorates,
if they decompose, either to another chlorate and oxygen, or to chloride
and oxygen (redox).
Hydroxide,
if it decomposes, to oxide and water (not redox)
