KMnO₄ acts as an oxidising agent in alkaline medium. When alkaline KMnO₄ is treated with KI, iodide ion is oxidised to .........

1.	$ I_{2}$	2.	$ I O^{-}$
3.	$ I O_{3}^{-}$	4.	$I O_{4}^{-}$

$K M n O_{4}$ acts as an oxidising agent in alkaline medium.When alkaline $K M n O_{4}$ is treated with KL, iodide ion i oxidised to $I O_{3}^{-}$ $R e a c t i o n 2 K M n O_{4} + H_{2} O + K I \to 2 M n O_{4} + 2 K O H + K I O_{3}$
$o r, I^{-} + 6 O H^{-} \to I O_{3}^{-} + 3 H_{2} O + 6 e^{-}$
