`KMnO_(4)` acts as an oxidising agent in alkaline medium. When alkaline `KMnO_(4)` is treated with KI, iodide ion is oxidised to

A

`I_(2)`

B

`IO^(-)`

C

`IO_(3)`

D

`IO_(4)^(-)`

Text Solution

Verified by Experts

The correct Answer is:
C
`Cr^(3+) : 3d^(3)`
`mu = sqrt(n(n+1)) B.M.`
` = sqrt(3(3+2))`
` = 3.87` B.M.
