Question

Number of moles of ferrous sulphate oxidised by 1 mole of potassium permanganate in acidic medium is


(1)2/5
2) 5/2
3) 1/5
(4) 5

​

Answer 1

Answer:

4

Explanation:

The reaction between Ferrous sulphate & potassium permanganate is given as :

2KMnO4 + 8H2SO4+10FeSO4 →K2SO4 + 2MnSO4 + 8H2O+5Fe(SO4 )3

Therefore, by stiochiometry,

2 moles of KMnO4 ≡ 10 moles of FeSO4

Therefore, 1 mole of KMnO4 ≡ 5 moles of FeSO4

Therefore, 5 moles of ferrous sulphate are oxidized by 1 mole of potassium permanganate in acidic medium.
