preparation of oxygen from potassium nitrate

The common name of potassium nitrate is Bengal salt petre or nitre. It can be prepared by treating the oxide, hydroxide, carbonate or hydrogen carbonate salts of potassium with nitric acid. It is a colorless crystalline solid, soluble in water. When heated, ..

Metallic nitrates, when heated, give out oxygen. At the same time, most of them also give out a reddish brown gas - nitrogen dioxide, NO2. Thus, these nitrates cannot be used to prepare oxygen. However, sodium and potassium..
