| August 15, 2021 | education
General nitrate formula; MeNO3, where Me is metal.
Decompose when heated according to the scheme:
1. Nitrates of metals standing in the range of activity to magnesium (mainly alkali metals). For example, potassium:
2KNO3 = 2KNO2 + O2 (nitrite + oxygen).
2. Standing in the row of activities between magnesium and copper, including them: 2Pb (NO3) = 2PbO + 4NO2 + O2 (metal oxide, nitrogen oxide (IV), oxygen).
3. After copper: 2AgNO3 = 2Ag + 2NO2 + O2 (metal, nitrogen oxide (IV), oxygen).
