`KMnO_(4)` is a strong oxidising agent in acidic medium. To provide acidic medium, `H_(2)SO_(4)` is used instead of HCl. This is because

A

` IO_(3)^- `

B

`I_(2)`

C

`IO_(4)`

D

`IO`

Text Solution

Verified by Experts

The correct Answer is:
B
`2K_(2)MnO_(4) + 2KOH to 2K_(2)MnO_(4) + H_(2)O +O`
`2K_(2),MnO_(4), +2H_(2),O to 2MnO_(2), +4KOH+ 20`
`2KMnO_(4), +H_(2)Ooverset(alkaline) to 2MnO_(2) + 2KOH+3[O]`
`KI+[O] to KIO_(3)`
2KMnO_(4) +KI+H_(2)O to 2KOH + 2MnO_(2) +KIO_(3)`
