Given that, E _ O _ 2 / H _ 2 O ^ o = + 1 .23 V; E _ S _ 2 O _ 8 ^...

Given that,

EO2/H2Oo=+1.23V;{E}_{{O}_{2} / {H}_{2}O}^{o} = + 1 .23 V;
ES2O82−/SO42−o=2.05V{E}_{{S}_{2}{O}_{8}^{2 -} / {SO}_{4}^{2 -}}^{o} = 2 .05 V
EBr2/Br−o=+1.09V;{E}_{{Br}_{2} / {Br}^{-}}^{o} = + 1 . 09V;
EAu3+/Auo=1.4V{E}_{{Au}^{3 +} / Au}^{o} = 1 .4 V


The strongest oxidizing agent is

Options

  1. AO2{O}_{2}
  2. BS2O82−{S}_{2}{O}_{8}^{2 -}
  3. CBr2B{r}_{2}
  4. DAu3+A{u}^{3 +}

Correct answer

B. S2O82−{S}_{2}{O}_{8}^{2 -}

Step-by-step solution

For strongest oxidizing agent, the standard reduction potential should be highest.

An oxidizing agent, or oxidising agent is a substance that has the ability to oxidize other substances — in other words to accept their electrons. Common oxidizing agents are oxygen, hydrogen peroxide and the halogens.
