Explain why: (i) E^0 for Mn^(3+)//Mn^(2+) couple is more positive than that for Fe^(3+)//Fe^(2+). (At. Nos. Mn = 25, Fe = 26). (ii)Ce^(3+) can be easily oxidised to Ce^(4+). (At. No. Ce = 58). |
| Answer» SOLUTION :(ii) `CE^(3+)` ions having the configuration `4F^(1)d^(0)6d^(0)` can easily lose election to acquire the configuration `4f^0 5d^(0) 6s^(0)` and FORM `Ce^(4+)`ION. | |
