Other Oxides

wallpapers Resource 2020-12-01
Oxides are compounds (of course they must be pure). Its composition contains only two elements, one of which must be oxygen element, if the other is a metal element, it is called a metal oxide; if the other is not a metal element, it is called a non-metal oxide.
 
Ozonide
 
Common ozonides are mostly relatively active alkali metal oxides, such as KO3, CsO3, RbO3, etc. They are named after the preparation of ozone and alkali metal hydroxides. Alkali metal ozonides decompose slowly at room temperature to produce superoxide and oxygen.
 
Potassium ozonide
 
The dry K hydroxide reacts with O3 to generate ozonides:
6KOH + 4O3 = 4KO3+ 2KOH·H2O + O2
Potassium ozonide is an orange-red paramagnetic crystal, which can be regarded as a solid carrier of oxygen and is used as a high-energy oxidant. Placed at room temperature, it will slowly decompose into potassium superoxide and oxygen.

These compounds meet the definition of oxides in terms of their molecular composition, but the valences of oxygen in the molecule are +2 and +1 respectively. They are electron providers rather than gainers, so they are not called oxides. In order to explain the phenomenon that conforms to the definition of oxide but is not an oxide, we call this type of compound a similar oxide.
For example, oxyfluoride compounds are now known as oxygen difluoride (OF2), dioxygen difluoride (O2F2), trioxygen difluoride (O3F2), tetraoxyfluoride (O4F2) and pentaoxy difluoride (O5F2) ).
Except for oxygen difluoride, other oxyfluorides are unstable. Oxygen difluoride is a nearly colorless or light yellow gas.Oxides are compounds (of course they must be pure).
