Question

The compounds formed at anode in the electrolysis of an aqueous solution of potassium acetate are

• A. $CH_4$ and $H_2$
• B. $CH_4$ and $CO_2$
• C. $C_2H_6$ and $CO_2$
• D. $C_2H_4$ and $Cl_2$

Answer 1

Answer: (C)

$C_2H_6$ and $CO_2$

Answer 2

It is a Kolbe?? synthesis $CH_{3}COOK {<=>} CH_{3}COO^{-}+K^{+}$ At anode : $2CH_{3}COO^{-} \to CH_{3}-CH_{3}-CH_{3}+2CO_{2}+2e^{-}$ At cathode : $2K^{+}+2e^{-} \to 2K { ->[2H_{2}O] }2KOH+H_{2}$
