Consult the table of standard electrode potential and suggest three substances that can oxidise ferrous ions under suitable conditions. |
| Answer» Solution :Form the table it is seen that `E_(Fe(3+))^o//Fe^2=0.77V`When OXIDATION occurs in this couple, STANDARD electrode potential will be -0.77V.i.e.,`E_(Fe(2+))^o//Fe^(2+)=-0.77`.Those substances which are stronger oxidising agents only can bring about this oxidation. EXAMPLE of such oxidising agents are `Br_2,Cl_2,F_2`,etc. | |
