Manganese exhibits oxidation states of +2,+3,+4,+6 and +7 So, in acidic medium on reaction of MnO 4- with H 2 O 2 it changes from 7 to 2 .

Q. What is the change in the oxidation state of $M n$ in the reaction of $M n O_{4}^{-}$ with $H_{2} O_{2}$ in acidic medium?

$7 \to 4$

$6 \to 4$

$7 \to 2$

$6 \to 2$

Manganese exhibits oxidation states of $+ 2, + 3, + 4, + 6$ and $+ 7$

So, in acidic medium on reaction of $M n O_{4}^{-}$ with $H_{2} O_{2}$ it changes from $7$ to $2$ .
