`KMnO_(4)` oxidises `I^(-)` to `I_(2)` in acidic medium. The equivalent weight of `KMnO_(4)` is :

A

`10^(-3)`

B

`10^(-4)`

C

`2.5xx10^(-4)`

D

`2.5xx10^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
C
Eq. of `Hg_(5)(IO_(6))_(2)`=Eq. of `I_(2)`=Eq. of `Na_(2)S_(2)O_(3)`
`:. ` (moles of `Hg_(5)(IO_(6))_(2)`)`xx16=0.004xx1`
`:. ` moles of `Hg_(5)(IO_(6))_(2)=2.5xx10^(-4)`.
