2 moles ofFeSO4in acid medium are oxidized by x moles ofKMnO4, whereas 2 moles ofFeC2O4in acid medium are oxidized by y moles ofKMnO4. The ratio of x and y is

Options:

Answer:
A
Solution:

Fe2+→Fe3++e
Mn7++5e→Mn2+
5moleFeSO4≡1moleMn7+
2moleFeSO4≡25=x
Also
Fe2+→Fe3++e
C3+2→2C4++2e
Mn7++5e→Mn2+
5moleFeC2O4=3moleMn7+
2moleFeC2O4=35×2=y
xy=13
