The E0 values at

{25^0}C

for

{A^ + }/A,\mathrm{ }{B^{2 + }}/B,\mathrm{ }{D^{3 + }}/D

and

{E^ + }/E

are -2.15, -1.75, +0. 15 and +0.21 volt respectively. Which of the following is the strongest oxidising agent ?

View answer and explanation

Correct option: A

{E^ + }

Option A is correct because the strongest oxidizing agent is the one with the highest (most positive) standard reduction potential. Among the given options, E+ has the highest value (+0.21 V), indicating it has the greatest tendency to be reduced and thus is the strongest oxidizing agent.
