Potassium superoxide, KO₂, is utilised in closed system breathing apparatus. Exhaled air contains CO₂ and H₂O, both of which are removed and the removal of water generates oxygen for breathing by the reaction 4KO₂(s) + 2H₂O(1)→ 30₂(g) + 4KOH(s) The potassium hydroxide removes CO₂ from the apparatus by the reaction : KOH (s) + CO₂(g) → KHCO3(s) What mass of KO, generates 20 gm of oxygen ?
