Question

Which of the following is the strongest oxidising agent.

• A. $BrO_{3}^{-}/Br^{2 +},E^{o} = + 1.50$
• B. $Fe^{3 +}/Fe^{2 +},E^{o} = + 0.76$
• C. $MnO_{4}^{-}/Mn^{2 +},E^{o} = + 1.52$
• D. $Cr_{2}O_{7}^{2 -}/Cr^{3 +},E^{o} = + 1.33$

Answer 1

Answer: (C)

$MnO_{4}^{-}/Mn^{2 +},E^{o} = + 1.52$

Answer 2

Higher is the reduction potential stronger is the oxidising agent. Hence in the given options. $MnO_{4}^{-}$ is strongest oxidising agent.
