Question

What is the change in the oxidation state of $Mn$ in the reaction of $MnO _{4}^{-}$ with $H _{2} O _{2}$ in acidic medium?

• A. $7 \rightarrow 4$
• B. $6 \rightarrow 4$
• C. $7 \rightarrow 2$
• D. $6 \rightarrow 2$

Answer 1

Answer: (C)

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$ .
