H₂O₂ is manufactured these days by
Options
(a) the action of H₂O₂ on BaO₂
(b) the action of H₂SO₄ on Na₂O₂
(c) electrolysis of 50% H₂SO₄
(d) burning hydrogen in excess of oxygen
Correct Answer:
electrolysis of 50% H₂SO₄
Explanation:
Electrolysis of 50% sulphuric acid is the commercial method for the preparation of hydrogen peroxide.
H₂SO₄ ⇌ H⁺ + HSO₄⁻,
At anode : 2HSO₄⁻ → H₂S₂O₈ + 2e⁻,
H₂S₂O₈ + 2H₂O → 2H₂SO₄ + H₂O₂,
At cathode : 2H + 2e⁻ → H₂
