Water undergoes electrolysis, producing H+H^+H+ and OH−OH^-OH− ions
H+H^+H+ (hydrogen ions) and OH−OH^-OH− (hydroxide ions)
The less reactive ion
The ion that can be oxidised more easily
Cu2+Cu^{2+}Cu2+ (copper less reactive than hydrogen)
Solid copper (deposits on cathode)
OH−OH^-OH− (no halide ions present)
Oxygen gas and water
H+H^+H+ (sodium more reactive than hydrogen)
Hydrogen gas
Cl−Cl^-Cl− (chloride ions are halide ions)
Chlorine gas
OH−OH^-OH− ions, producing oxygen gas
