Electrolysis of molten sodium chloride: yield sodium and chlorine.
Electrolysis of sodium chloride water solution: yield hydrogen, sodium hydroxide and chlorine.
sodium metal is deposited at the cathode.
Many salts in solution or molten are electrolytes.
Aluminum and magnesium are the two metals in greatest volume that are produced by electrolyzing their molten salts.
When molten aluminum oxide is electrolyzed, it forms aluminum metal at the cathode and oxygen gas at the anode. This process is used in the extraction of aluminum from bauxite ore.
The products are sodium hydroxide and hydrogen.
When a mixture of 42% NaCl and 58% CaCl2 is electrolysed in Down'cell pure molten sodium metal is obtained.
In solid state, Aluminium and oxide ions are immobile. When aluminum oxide is melt down,aluminum and oxide ions become free and they can easily migrate to respecve electrodes. Therefore, aluminum oxide is electrolysed in molten state.
For example salts dissociated in water are electrolytes. Also some molten salts etc.

Ionic compounds that are either molten or dissolved in a solvent can be electrolyzed. This allows the ions in the compound to move freely and conduct electricity. Covalent compounds are generally not electrolyzed because they do not dissociate into ions in solution.
For example chlorides of sodium, calcium, potassium.
