Question

A solution of 10 mL of `(M)/(10) FeSO_(4)` was titrated with `KMnO_(4)` solution in acidic medium, the amount of `KMnO_(4)` used will be :
A. 10 mL of 0.5 M
B. 10 mL of 0.1 M
C. 10 mL of 0.02 M
D. 5 mL of 0.1 M

Answer 1

Correct Answer - C
The involved reaction is :
`2KMnO_(4)+8H_(2)SO_(4)+10FeSO_(4) to 5Fe_(2)(SO_(4))_(3)+2MnSO_(4)+K_(2)SO_(4)+8H_(2)O`
`(M_(1)V_(1))/(2)=(0.1xx10)/(10)`
`M_(1)V_(1)=0.2` which is possible in (c )
