4. Why is Mn2+ not readily oxidised to Mn3+?
- This is because the electronic configuration of Mn2+ is more stable than that of Mn3
- This is because the electronic configuration of Mn2+ is less stable than that of Mn3
- This is because Mn2+ does not have any more electrons in its d orbitals
- This is because the Mn2+ cannot accept any more electrons in to its d orbital
