What is the change in the oxidation state of \(\mathrm{Mn}\) in the reaction of \(\mathrm{MnO}_4^{-}\)with \(\mathrm{H}_2 \mathrm{O}_2\) in acidic medium?
- A \(7 \rightarrow 4\)
- B \(6 \rightarrow 4\)
- C \(7 \rightarrow 2\)
- D \(6 \rightarrow 2\)
Answer & Solution
Correct Answer
(C) \(7 \rightarrow 2\)
Step-by-step Solution
Detailed explanation
Manganese exhibits oxidation states of \(+2,+3,+4,+6\) and +7 . \(\mathrm{So}\), in acidic medium on reaction of \(\mathrm{MnO}_4^{-}\)with \(\mathrm{H}_2 \mathrm{O}_2\) it changes from 7 to 2 .
