Question:medium
The charge required for the reduction of 1 mol of \( MnO_4^- \) to \( MnO_2 \) is
The charge required for the reduction of 1 mol of \( MnO_4^- \) to \( MnO_2 \) is
Show Hint
The number of Faradays required for a redox reaction corresponds to the total number of electrons involved in the oxidation or reduction of the species.

- 1 F
- 3 F
- 5 F
- 6 F
Show Solution
The Correct Option is C
Solution and Explanation
During the reduction of \( MnO_4^- \) to \( MnO_2 \), the oxidation state of the manganese ion changes from +7 to +4. This change requires 5 moles of electrons, corresponding to a charge of 5 F (Faradays).
Step 2: Therefore, option (3) is the correct answer.
Step 2: Therefore, option (3) is the correct answer.
