← ScienceWhich consequence results during water electrolysis using alkaline electrolyte?
A)Hydrogen gas forms at cathode✓
B)Overpotential increases for oxidation
C)Electrode passivation reduces current
D)Electrolyte conductivity irreversibly decreases
💡 Explanation
Hydrogen liberation occurs at cathode because electrons reduce water molecules, forming hydroxide ions and hydrogen gas due to the electron transfer mechanism. Therefore, hydrogen emerges at cathode, rather than oxygen, which forms at the anode.
