In acidic medium, MnO4- reduces is Mn2+ and oxidises I- to I2. ∴ KI + MnO4- xrightarrowH+ I2 + Mn2+ In basic medium, MnO4- reduces to MnO2 and produces IO3-. ∴ KI + MnO4- xrightarrowOH- MnO2 + IO3-

Q. Identify $P$ and $Q$ products in given reaction
$K I + M n O_{4}^{-} H^{+} P + M n^{2 +}$
$K I + M n O_{4}^{-} O H^{-} I O_{3}^{-} + Q$

$I O_{3}^{-}, M n O_{2}$ respectively

$I_{2}, M n^{2 +}$ respectively

$I O_{3}^{-}, M n^{2 +}$ respectively

$I_{2}, M n O_{2}$ respectively

In acidic medium, $M n O_{4}^{-}$ reduces is $M n^{2 +}$ and oxidises $I^{-}$ to $I_{2}$ .
$∴ K I + M n O_{4}^{-} H^{+} I_{2} + M n^{2 +}$
In basic medium, $M n O_{4}^{-}$ reduces to $M n O_{2}$ and produces $I O_{3}^{-}$ .
$∴ K I + M n O_{4}^{-} O H^{-} M n O_{2} + I O_{3}^{-}$
