In acidic medium, `KMnO_4` oxidises `FeSO_4` solution. Which of the following statements is correct?
A. 10 mL of 1 N `kMnO_4` solution oxidises 10 mL of 5 N `FeSO_4` solution.
B. 10 mL of 1 M `KMnO_4` solution oxidises 10 mL of 5 M `FeSO_4` solution.
C. 10 mL of 1 M `KMnO_4` solution oxidises 10 mL of 1 M `FeSO_4` solution.
D. 10 mL of 1 N `KMnO_4` solution oxidises 10 mL of 0.1 M `FeSO_4` solution.

Correct Answer - B
`2KmO_4+8H_2SO_4+10FeSO_4 to K_2SO_4+2MnSO_4+5Fe_2(SO_4)_3+8H_2O`
One mole of `KMnO_4` oxidises five mole of `FeSO_4` i.e. 1M `KMnO_4` can oxidise equal amount5 of 5 M `FeSO_4`.
