What is the correct representation of reaction occurring when HCl is heated with MnO2?
- MnO4– + 5Cl– + 8H+ → Mn2+ + 5Cl– + 5H2O
- MnO2 + 2Cl– + 4H+ → Mn2+ + Cl2 + 2H2O
- 2MnO2 + 4Cl– + 8H+ → 2Mn2++ 2Cl2 + 4H2O
- MnO2 + 4HCl → MnCl4 + Cl2 + H2O
Answer
(B) MnO 2 + 2Cl – + 4H + → Mn 2+ + Cl 2 + 2H 2 O
