Solved: CHEMISTRY Question for NEET

neet CHEMISTRYMedium

In the neutral or faintly alkaline medium, $KMnO_4$ oxidises iodide into iodate. The change in oxidation state of manganese in this reaction is from

$+7$ to $+4$

$+7$ to $+3$

$+7$ to $+2$

$+6$ to $+4$

Step-by-Step Solution

In neutral or faintly alkaline medium, $KMnO_4$ acts as an oxidizing agent and gets reduced to $MnO_2$ . The oxidation state of Mn in $KMnO_4$ is $+7$ and in $MnO_2$ is $+4$ . Thus, the change is from $+7$ to $+4$ .
