Take Free Practice Test On 2026 JAMB UTME, Post UTME, WAEC SSCE, GCE, NECO SSCE
  • A Hydrogen gas at the cathode and chlorine gas at the anode
  • B Hydrogen gas at the cathode and oxygen gas at the anode
  • C Sodium metal at the cathode and chlorine gas at the anode
  • D Sodium metal at the cathode and oxygen gas at the anode
Correct Answer: Option B
Explanation:
During the electrolysis of aqueous sodium chloride using inert electrodes (such as platinum or carbon), the cations (H\(^+\)) are attracted to the cathode and are reduced to form hydrogen gas (H\(_2\)). The anions (OH\(^-\)) are attracted to the anode and are oxidized to form oxygen gas (O\(_2\)).
