The `E^(@)` value in respect of the electrodes `(Z=24)`, manganese `(Z=25)` and iron `(Z=26)` are : `Cr^(3+)//Cr^(2+)=-0.4V,Mn^(3+)//Mn^(2+)=+1.5V`,`Fe^(3+)//Fe^(2)=+0.8V`. On the basic of the above information compare the feasibilities of further oxidation of their `+2` oxidation states. |
| Answer» `+2` oxidation state of Mn is mores stable than `+2` oxidation state of Fe which, in turn, is more stable that `+2` oxidation state of `Cr`. So the order of feasibility of further oxidation of `+2` oxidation state is `Cr^(2+)gtFe^(2+)gtMn^(2+)` | |
