Which of the following Cations is the best oxidizing agent and which is the worst?

a) Pb⁺²

b) Cr⁺³

c) Fe⁺²

d) Sn⁺²

Solutions

Expert Solution

Eo (Pb2+/Pb) = -0.126 V
Eo (Cr3+|Cr) = -0.74 V
Eo (Fe2+/Fe) = -0.44 V
Eo (Sn2+/Sn) = -0.13 V

greater Eo value means good oxidising agent
Eo value is largest for Pb. SO Pb2+ is beat oxidising agent

similarly worst is Cr3+
