Explain the mechanism of electrolysis of molten sodium hyroxide

Answer»

Solution :Molten SODIUM hydroxide dissociates to give `NA^(+) and OH^(-)` ions. `Na^(+)` ions go towards cathode while `OH^(-)` ions go towards anode.
REACTION at anode : `4OH^(-) rarr 2H_(2)O + O_(2) + 4E^(-)`
Reaction at cathode : `4Na^(+) + 4e^(-) rarr 4Na`
