In acidic medium, KMnO(4) oxidises FeSO(...

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 5M `FeSO_4` solution

C

10 ml of 1M `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.

Text Solution

Verified by Experts

The correct Answer is:
B
`2KMnO_(4)+8H_(2)SO_(4)+10FeSO_(4)rarr K_(2)SO_(4)+2MnSO_(4)+5Fe_(2)(SO_(4))_(3)+8H_(2)O`
One mole of `KMnO_(4)` oxidises five moles of `FeSO_(4)` i.e. 1 M `KMnO_(4)` can oxidise equal amount of 5M `FeSO_(4)`.
