Kaliumozonid , KO ₃ , is a red salt of potassium from the group of ozonides .

Extraction and presentation

The salt can be obtained through the reaction of potassium hyperoxide and ozone .

${\displaystyle {\ce {KO2 + O3 -> KO3 + O2}}}$

properties

Physical Properties

The crystal system is isostructural with potassium azide and tetragonal with the space group I 4 / mcm (space group no. 140) .

Chemical properties

Potassium ozonide reacts with water. This creates potassium hydroxide and oxygen .

${\displaystyle {\ce {2 KO3 + H2O -> 2 KOH + O2}}}$

At room temperature, potassium ozonide decomposes to potassium hyperoxide and oxygen within 11 days. This process lasts only 30 minutes at 60 ° C.
