RUBIDIUM SUPEROXIDE RbO2

Properties Rubidium superoxide RbO2:

The orange-yellow. Decomposes when heated, melts under excess pressure of O2. Ion has the structure of (Rb +) (O2-). Reacts vigorously with water, acids, ozone, mono and carbon dioxide, ammonia. It is a strong oxidizing agent.

 

Obtaining rubidium superoxide RbO2:

Rb + O2 (air) = RbO2 (combustion).

4 Rb + O2 = 2 Rb2O (in the cold), Rb → (O2) Rb2O2 →(O2) , (time) RbO2↓ (-50° C, in the liquid NH3).

4 RbOH (liquid) + 3 O2 = 4 RbO2 + 2 H2O (450° C),

 

Сhemical reactions with rubidium superoxide RbO2:

RbO2 (-O2)→ (400—800° C) Rb2O2 (-O2)→(t> 1010° C) Rb2O,

2 RbO2 = Rb2O2 + O2 (290° C, vacuum).

2 RbO2 + H2O = RbOH + RbHO2 (solution) + O2↑ (0° C),

2 RbHO2 (solution) →(time) 2 RbOH + O2↑ (normal temp.).

4 RbO2 + 2 H2O (combustion) = 4 RbOH + 3O2↑.

2 RbO2 + 2 HCl (diluted, cold) = 2 RbCl + H2O2 + O2↑.

2 RbO2 + 2 H2SO4 (anhydrous) = 2 RbHSO4 + O3↑ + H2O (normal temp.).

4 RbO2 + 2 CO2 (humid) = 2 Rb2CO3 + 3O2 (normal temp.),

2 RbO2 + CO = Rb2CO3 + O2 (30—40° C).

RbO2 + O3 = RbO3 + O2 (normal temp.).

2 RbO2 + 2 NH3 →(time) 2RbOH + N2 + 2H2O (normal temp.).
