Question

How can Mn²⁺ be oxidized to Mn⁷⁺? (keep in mind Mn⁷⁺ is a very strong oxidizing agent). Provide half reactions to show the overall reaction. (Inorganic Chemistry)

Expert Solution

Step 1

Mn²⁺ can be converted to Mn⁷⁺ by reacting with a strong oxidizing agent like PbO₂.

The reaction occurring is:

$5 {PbO}_{2} + 2 Mn {({NO}_{3})}_{2} + 6 {HNO}_{3} \to 2 {HMnO}_{4} + 5 Pb {({NO}_{3})}_{2} + 2 H_{2} O$
