Key Points: Oxygen and Compounds of Oxygen

oxygen (O₂)

Preparation:

  • Heating potassium chlorate:
    KClO₃ → O₂ (MnO₂ catalyst)
  • Electrolysis of water

Chemical Properties:

  • With metals → metal oxides
    2Ca + O₂ → 2CaO
    4Al + 3O₂ → 2Al₂O₃
  • With non-metals → non-metal oxides
    C + O₂ → CO₂
    P₄ + 5O₂ → P₄O₁₀
  • With HCl:
    4HCl + O₂ → 2H₂O + 2Cl₂
  • Oxidation reaction:
    2SO₂ + O₂ → 2SO₃ (V₂O₅ catalyst)

Types of Oxides:

Type Nature Examples
Acidic Form acids in water SO₂, CO₂, N₂O₅
Basic Form bases in water Na₂O, CaO, BaO
Amphoteric Both acidic & basic Al₂O₃
Neutral Neither acidic nor basic CO, NO, N₂O
