Which of the following is used to prepare Cl₂ gas at room temperature from concentrated HCl
Options
(a) MnO₂
(b) H₂S
(c) KMnO₄
(d) Cr₂O₃
Correct Answer:
KMnO₄
Explanation:
KMnO₄ oxidised halogen acids to halogen. 2KMnO₄ + 3H₂SO₄ → K₂SO₄ + 2MnSO₄ + 3H₂O + 5O, [2HCl + O → H₂O + Cl₂] * 5. 2KMnO₄ + 3H₂SO₄ + 10HCl → K₂SO₄ + 2MnSO₄ + 8H₂O + 5Cl₂.
Therefore KMnO₄ is used to prepare Cl₂ from concentrated HCl.
