Number of moles of

MnO_4^ -

required to oxidize one mole of iodide ion completely in acidic medium is

View answer and explanation

Correct option: A

1/5 mole

Option A (1/5 mole) is correct because the balanced redox reaction shows that 2 moles of

MnO_4^ -

are required to oxidize 10 moles of iodide ions, thus 1/5 mole is needed for one mole of iodide.
