The products formed at the cathode and anode by electrolysis of aqueous NaCl solution respectively are
Answer & explanation
Correct answer: option 3
Electrolysis of aqueous NaCl
\(NaCl (s) —————→ Na^+(aq) + Cl^− (aq)\)
At cathode
\(2H_2O (l) + 2e^— —————→ H_2 ↑ + 2OH^—\)
At anode
\(2Cl^— —————→ Cl_2 + 2e^—\)
\(Na^+ OH^— —————→ NaOH\)
