POTASSIUM SUPEROXIDE KO2

Properties potassium superoxide KO2:

The orange-yellow, decomposes when heated, melts under excess pressure. It has the ionic structure (K +) (O2-). Reacts with water, acids, mono-and carbon dioxide, ozone, potassium, ammonia. It is a strong oxidizing agent.


Obtaining potassium superoxide KO2:

K + O2(air) = KO2 (combustion, impurity K2O2).


Chemical reactions with potassium superoxide KO2:

KO2 -O2→(290°C, vacuum) K2O2 -O2 → (530°C) K2O.

2KO2 + H2O = КОН + KHO2 (solution) + O2↑ (0°C),

2KHO2 (solution) → time → 2KОН + O2↑ (normal temp.).

4KO2 + 2H2O (burning) = 4KОН + 3O2↑.

2KO2 + 2HСl (diluted, cold) = 2KСl + H2O2 + O2↑.

2KO2 + H2SO4 (anhydrous) = K2SO4 + O3↑ + H2O (normal temp.).

KO2 + O3 = KO3 + O2 (until 0°C, in the liquid CCl2F2).

2KO2 + S = K2SO4 (130—140°C),

2KO2 + SO2 = K2SO4 + O2 (100°C).

4KO2 + 3C (graphite) = 2K2CO3 + CO2 (30°C).

4KO2 + 2CO2 (humidity) = 2 K2CO3 + 3O2 (normal temp.).

2KO2 + СO = K2CO3 + O2 (50°C).

2KO2 + 2 NO2 = 2KNO3 + O2 (70°C).

KO2 + 3K = 2 K2O (700°C, pressure).

2KO2 + 2NH3 → time → 2KOH + N2 + 2H2O (normal temp.).

Lightning strikes produce O3, which is ozone, and strengthen the ozone layer of the atmosphere.
