Standard electrode potentials are `Fe^(2+)//Fe, E^(@) = -0.44 V` `Fe^(3+)//Fe^(2+), E^(@) = +0.77 V` If `Fe^(3+), Fe^(2+)`, and Fe block are kept together, thenA. `Fe^(3+)` increasesB. `Fe^(3+)` decreasesC. `Fe^(2+)//Fe^(3+)` remains unchangedD. `Fe^(2+)` decreases. |
|
Answer» Correct Answer - B As `E(Fe^(3+)//Fe^(2+))` is more than ` E(Fe^(2+)//Fe),therefore Fe^(3+)` will get reduced and Fe will get oxidsied As such `Fe^(3+)` will decrease. |
