Q. Which of the statement is incorrect if electrolysis of $CH _{3}$ COONa (aq.) is made using Pt electrodes?

KEAMKEAM 2019

Solution:

At anode:

$2 CH _{3} COO ^{-} \longrightarrow C _{2} H _{6}+2 CO _{2( g )}+2 e^{-}$

At cathode $: 2 H ^{+}+2 e^{-} \longrightarrow H _{2(g)}$

$\therefore CO _{2}: H _{2}=2: 1$
