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