Vedclass · Answer

(A) The electrolysis of an aqueous solution of sodium acetate is known as the Kolbe electrolysis reaction. The overall reaction is: $2CH_3COONa + 2H_2O \rightarrow CH_3-CH_3 + 2CO_2 + H_2 + 2NaOH$. At the anode,the acetate ion $(CH_3COO^-)$ undergoes oxidation to form ethane and carbon dioxide $(CO_2)$. The reaction at the anode is: $2CH_3COO^- \rightarrow CH_3-CH_3 + 2CO_2 + 2e^-$. Therefore,$CO_2$ gas is evolved at the anode.

Which of the following gases is evolved at the anode during the electrolysis of sodium acetate?
