Which reaction does not involve a redox process?

Options

Choose one · Correct answer highlighted

2Na + 2H₂O → 2NaOH + H₂ Fe + 2HCl → FeCl₂ + H₂ MgSO₄ + 2NaOH → Mg(OH)2 + Na₂SO₄ Correct 2H₂O₂ → 2H₂O + O₂

Explanation

In MgSO₄ + 2NaOH → Mg(OH)2 + Na₂SO₄, no element changes oxidation state; it’s a double displacement reaction.
