A. Sodium
B. Hydrogen
C. Chlorine
D. Oxygen
E. Peroxide

Asked by Agatha934

Answer (2)

The answer is Hydrogen

Answered by michaelwilson19 | 2024-06-10

The product formed at the cathode during the electrolysis of a dilute aqueous sodium chloride solution is hydrogen gas (H₂), not sodium. This occurs because water is reduced at the cathode, producing H₂ gas. Therefore, the correct answer is B. Hydrogen.
