Number of moles of MnO ₄⁻ required to oxidise one mole of ferrous oxalate completely in acidic medium will be

Options

  1. A0.6 mole
  2. B0.4 mole
  3. C7.5 moles
  4. D0.2 mole

Correct answer

A. 0.6 mole

Step-by-step solution

Key Idea : MnO ₄⁻+5 C ₂ O ₄²⁻+24 H ⁺ 3 Mn ²⁺+10 CO ₂+12 H ₂ O Number of moles of MnO ₄⁻ required to oxidise 5 moles of C ₂ O ₄²⁻=3 Number of moles of MnO ₄⁻ required to oxidise 1 mole of C ₂ O ₄²⁻= 3 5 =0.6 ~mol
