Question

Use the data given below and find out which of the following is the strongest oxidizing agent.

$Eº_{CrO_{7}^{2 -}/Cr^{3 +}} = 1.33V;Eº_{Cl_{2}/Cl} = 1.36V$

$Eº_{MnO_{4}^{-}/Mn^{2 +}} = 1.51V;Eº_{Cr^{3 +}/Cr} = - 0.74V$

• A. $Cl^{- 1}$
• B. Cr
• C. $MnO_{4}^{-}$
• D. $Cr^{3 +}$

Answer 1

Answer: (C)

$MnO_{4}^{-}$

Answer 2

Higher the reduction potential value greater is the tendency to undergo reduction i.e. stronger will be the oxidizing agent. Thus, $MnO_{4}^{-}$ is the strongest oxidizing agent.
