WebThis may well be due to the potassium reacting faster than the others and an oxide coating being formed almost as soon as you begin to heat it. In air: 4Li(s) + O 2 (g) → 2Li 2 O(s) Sodium and potassium produce a mixture of oxides, peroxides and super-oxides. In chlorine: 2Na(s) + Cl 2 (g) → 2NaCl(s) and similarly for the others. WebProduction. Potassium oxide is produced from the reaction of oxygen and potassium; this reaction affords potassium peroxide, K 2 O 2.Treatment of the peroxide with potassium produces the oxide: + Alternatively and more conveniently, K 2 O is synthesized by heating potassium nitrate with metallic potassium: + + Other possibility is to heat potassium …
