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

Options

A. `I_2`
B. `IO^(-)`
C. `IO_3^(-)`
D. `IO_4^(-)`

Answer

C

Explanation

`KMnO_4` acts as an oxidising agent in alkaline medium. When alkaline`KMnO_4` is treated with KI, iodide ion is oxidised to `IO_3^(-)`
Reaction :
`2KMnO_4 + H_2O + KI to 2MnO_4 + 2KOH + KIO_3`
`or, I^(-) + 6OH^(-) to IO_3^(-) + 3H_2O + 6e^(-)`.
