Vedclass · Answer

(B) Concentrated $H_2SO_4$ acts as an oxidizing agent when it undergoes reduction itself.In reaction $(B)$,$H_2SO_4$ oxidizes $HI$ to $I_2$ and is itself reduced to $SO_2$.The oxidation state of sulfur in $H_2SO_4$ decreases from $+6$ to $+4$ in $SO_2$,confirming its role as an oxidizing agent.In the other reactions ($A$,$C$,and $D$),$H_2SO_4$ acts only as an acid,as there is no change in the oxidation states of the sulfur atom.

In which of the following reactions does concentrated $H_2SO_4$ act as an oxidizing agent?
