The product of `I^(-)` with `MnO_(4) ^(-)` in alkaline medium is :

Options

A. `I _(2)`
B. `I O _(3) ^(-)`
C. `IO ^(-)`
D. `IO _(4) ^(-)`

Answer

B

Explanation

`KMnO _(4)` is strong oxidising agent. It can oxidise the iodide ion to
`I O _(3 ^(-) . ` When `I ^(-)` reacts with `MnO _(4)^(-)` in alkaline medium `IO _(3) ^(-) ` is formed.
`Mn O _(4) ^(-) + I ^(-) to IO _(3) ^(-) + M ^(2+)`
