How can hydrogen be produced by electrolysis of sodium hydroxide with graphite as an electrode?

Answer:

Because there is no hydrogen ions in the molten state of sodium hydroxide, sodium hydroxide and the onlyThis reaction should have occurred,Na+ + e=Na4OH-- 4e=O2+H2O
Molten sodium hydroxide is ionized out of Na+ and OH-, electrons are lost at the anode OH-, oxygen and water are produced (immediately evaporated at high temperature), and electrons are generated at Na+ at the cathode Na
You can think so, since sodium has been reduced, so there is always an atom is oxidized, it can only be oxygen oxidation reaction
