Vedclass · Answer

(B) An oxidizing agent is a substance that can accept electrons (its oxidation state decreases),while a reducing agent is a substance that can donate electrons (its oxidation state increases). For a compound to act as both,its central atom must be in an intermediate oxidation state. $1$. In $H_2O_2$,oxygen is in $-1$ state. It can go to $0$ (oxidizing) or $-2$ (reducing). $2$. In $SO_2$,sulfur is in $+4$ state. It can go to $+6$ (reducing) or $0$ (oxidizing). $3$. In $Cl_2$,chlorine is in $0$ state. It can go to $-1$ (oxidizing) or $+1$ (reducing). $4$. In $H_2$,hydrogen is in $0$ state. It can only be oxidized to $+1$ state. Therefore,$H_2$ acts only as a reducing agent.

Among the following,identify the compound which cannot act as both an oxidizing and a reducing agent.
