Question:medium

Which of the following change is not correct about the oxidizing property of $KMnO_4$ in acidic medium?

Show Hint

Remember the reduction products of $MnO_4^-$:

Acidic: $Mn^{2+}$ (Colourless)
Neutral/Faintly Alkaline: $MnO_2$ (Brown ppt)
Strongly Alkaline: $MnO_4^{2-}$ (Green)

Updated On: Mar 31, 2026

$S^{2-} \rightarrow S$
$Mn^{2+} \rightarrow MnO_2$
$SO_3^{2-} \rightarrow SO_4^{2-}$
$C_2O_4^{2-} \rightarrow CO_2$

Show Solution

The Correct Option is B
