The number of moles of KMnO₄ that will be needed to react with one mole of sulphite ion in acidic solution is
Options
(a) 4/5
(b) 2/5
(c) 1
(d) 3/5
Correct Answer:
2/5
Explanation:
The balanced equation is
2KMnO4 + 5 H2SO3 –> K2SO4 +2 MnSO4 +2 H2SO4 + 3H2O
From the above equation,
Moles of KMnO₄ required to oxidise 5 moles of H2SO₃ are 2
Moles of KMnO₄ required to oxidise 1 moles of H2SO₃ are 2/5
