Whichis strongerreducingagent Cr^(2+) orFe^(2+) ? |
|
Answer» Solution :When`CR^(2+)` and `Fe^(2+)`ACT asreducingagent`Cr^(2+) to Cr^(3+), Fe^(2+)to Fe^(3+)` The`E_(cr^(3+) // Cr^(2+))^(0) ` valueis `-0.41 V` and `E_(Fe^(3+)//Fe^(3+))^(0)` is +0.77V thismeansthat `Cr^(2+)`can beeasilyoxidizedto `Cr^(3+)` . But `Fe^(2+)`does not get oxidizedto `Fe^(3+)`easily . Therefore `Ce^(2+)`is abetterreducingagentthan `Fe^(3+)` |
