Passage / Comprehension

Using the data given below: $E_{Ce^{4 +} / Ce^{3 +}}^{\circ} = 1.61 V$ , $E_{Br_{2} / Br^{-}}^{\circ} = 1.09 V$ , $E_{Fe^{3 +} / Fe^{2 +}}^{\circ} = 0.77 V$ , $E_{Zn^{2 +} / Zn}^{\circ} = - 0.76 V$ .

Find out the strongest reducing agent.

Options:

Answer:

Solution:

Reducing power rises as the reduction potential of the couple falls. $Zn^{2 +} / Zn$ is lowest (-0.76 V), so $Zn$ is the strongest reducing agent.

Answer: (B).
