Question

What happens when chlorine comes in contact with NaOH during electrolysis of NaCl?

• A. NaCl is produced
• B. NaOCl is produced
• C. Both (a) and (b)
• D. None of the above

Answer 1

The correct option is C Both (a) and (b)

During electrolysis of $NaCl$, when $C{l}_2$ comes in contact with NaOH it produce both $NaCl$ and $NaOCl$.
$2NaOH+C{l}_2\to NaCl+NaOCl+H_{2}O$
To overcome this problem, the anode is separated from cathode in the electrolytic cell.
