Vedclass · Answer

(B) When sulfur dioxide $(SO_2)$ reacts with an acidic solution of potassium dichromate $(K_2Cr_2O_7)$,the sulfur dioxide acts as a reducing agent.In this reaction,the oxidation state of sulfur in $SO_2$ increases from $+4$ to $+6$ (in $SO_4^{2-}$),meaning $SO_2$ undergoes oxidation.Simultaneously,the chromium in $K_2Cr_2O_7$ is reduced from $+6$ to $+3$ $(Cr^{3+})$.Therefore,the overall process involves the oxidation of sulfur dioxide by potassium dichromate.

What type of reaction occurs when sulfur dioxide $(SO_2)$ reacts with an acidic solution of potassium dichromate $(K_2Cr_2O_7)$?
