Reduction of Permanganate Ion
The reduction of the permanganate ion (MnO4-) is a well-studied reaction in chemistry, particularly in redox reactions. The behavior of permanganate in different media influences the number of electrons involved in the reduction process.
1. Electrons in Neutral Medium
- In a neutral medium, the permanganate ion is reduced to manganese dioxide (MnO2).
- This reduction involves the transfer of 3 electrons.
2. Electrons in Alkaline Medium
- In alkaline conditions, the reduction of permanganate takes place to form manganese (MnO2) as well.
- This process involves the transfer of 1 electron.
3. Electrons in Acidic Medium
- In acidic solutions, permanganate is reduced to manganese(II) ions (Mn2+).
- This reduction involves the transfer of 5 electrons.
Summary of Electron Transfers
- 3 Electrons: Neutral medium (MnO4- to MnO2)
- 1 Electron: Alkaline medium (permanganate reduction)
- 5 Electrons: Acidic medium (MnO4- to Mn2+)
Correct Answer Explanation
The options A, C, and D are correct because they represent valid electron transfers in different media:
- Option A (3 electrons in neutral medium): Accurate for the reduction to MnO2.
- Option C (1 electron in alkaline medium): Correct for the simplified alkaline reaction.
- Option D (5 electrons in acidic medium): True for the complete reduction to Mn2+.
These details clarify the complexity of permanganate ion reduction based on the medium used in the reaction.
