Ammonium ozonide is an oxygen rich molecule containing an ammonium cation (NH4+) and an ozonide anion (O3−). Ammonium ozonide, like alkali ozonides, is a red solid.[1][2] Ammonium ozonide is stable at low temperatures, but it decomposes to ammonium nitrate at temperatures above -70 °C.[2]
Preparation and decomposition
[edit]Ammonium ozonide is made by bubbling gaseous ozone through liquid ammonia at -110 °C.[1][2] This method suffers from a low yield.[1]
- 12 NH3 + 11 O3 → 9 NH4O3 + 3 NO2
Ammonium ozonide decomposes into ammonium nitrate, oxygen gas, and water. If the above reaction is done at high temperatures, these decomposition products result immediately and no ozonide is formed.[1]
- 4 NH4O3 → 2 NH4NO3 + O2 + 4 H2O
