Question

Which one is wrong if electrolysis of $C{H}_{3}COONa\left(aq\right)$ is made using $Pt$ electrodes?

• A. $pH$ of solution increases
• B. Molar ratio of gases at anode and cathode is $3:1.$
• C. $\left[C{H}_{3}CO{O}^{\ominus }\right]$ in solution decreases.
• D. The molar ration of gases at anode and cathode is $2:1.$

Answer 1

The correct option is D The molar ration of gases at anode and cathode is $2:1.$

Sodium acetate undergoes electrolysis to form ethane gas, carbondioxide and hydrogen gas.

Hydrogen is liberated at cathode and ethane at anode.
