Thermal Decomposition of Sodium Nitrate
2NaNO3 → 2NaNO2 + O2
نظرة عامة
Sodium nitrate decomposes when heated above 380 C to form sodium nitrite and oxygen. This reaction illustrates the general behavior of nitrate salts, which release oxygen upon heating. Sodium nitrate (Chile saltpeter) was historically an important natural source of nitrogen for fertilizers and explosives.
