Question

In order to oxidize a mixture of one mole of each of FeC₂O₄ , Fe₂(C₂O₄)₃ , FeSO₄ and Fe₂(SO₄)₃ in acidic medium, the number of moles of KMnO₄ required is:
(A) 1 (B) 1.5
(C) 2 (D) 3

Answer 1

Answer:

D. will be correct answers

Explanation:

Mn+7 reduce to Mn+2 in acidic medium

so totall 5 electrons can transfer by 1 mole.

for total 16 + ions 5 kmno4 will be required.
