The number of moles of `KMnO_(4)` that will be needed to react with `1 mol` of sulphite ion in acidic solution is

A

`(2)/(5)`

B

`(3)/(5)`

C

`(4)/(5)`

D

1

Text Solution

Verified by Experts

The correct Answer is:
A
`5e^(-)+MnO_(4)^(ɵ)toMn^(2+)(n=5)`
`SO_(3)^(2-)toSO_(4)^(2-)+2e^(-)(n=2)`
" Eq of "`MnO_(4)^(ɵ)" Eq of "SO_(3)^(2-)`
`(1)/(5)mol=(1)/(2)mol`
`(2)/(5)mol=1mol`
