Question

1 mol of ferrous oxalate will require x mol of $KMn{O}_4$ in acidic medium, where x is:

• A. 0.6
• B. 0.8
• C. 0.9
• D. 1.2

Answer 1

The correct option is D 1.2

Balanced chemical reaction is shown below: 5 FeC₂O₄ + 6 KMnO₄ + 24 H₂SO₄ = 3 K₂SO₄ + 6 MnSO₄ + 5 Fe(SO₄)₃ + 24 H₂O + 10 CO₂

_{Hence, 1 mol of ferrous oxalate reacts with $1.2$ mole of $KMn{O}_4$}
