Chloride ions have a lower standard reduction potential than water, making them easier to oxidize at the anode compared to hydroxide ions. Therefore, chloride ions are preferentially discharged at the anode during the electrolysis of brine.
If you use potassium hydroxide instead of sodium hydroxide, you would make potassium salts instead of sodium salts. For example, if you reacted potassium hydroxide with hydrochloric acid, you would produce potassium chloride.
Sodium chloride does not react with water to produce sodium hydroxide because sodium chloride is a stable salt compound. The chemical structure of sodium chloride does not readily break down in water to form sodium hydroxide. Instead, sodium chloride dissociates into sodium and chloride ions in water due to its ionic nature.
During electrolysis of concentrated aqueous sodium chloride, chloride ions are preferentially oxidized over water molecules at the anode due to their higher standard electrode potential. This results in the liberation of chlorine gas instead of oxygen gas.
When an aqueous solution of sodium hydroxide is electrolyzed, hydrogen is produced at the cathode because hydrogen can be produced at a lower voltage than can sodium, and the supply of hydrogen from the water of the solution is sufficient to consume all the current supplied. When molten sodium chloride is electrolyzed, however, sodium is produced at the cathode.
Usually hydrogen will evolve from the cathode and oxygen from the anode, but if zinc is the anode, it may dissolve to produce zinc ions in the solution either instead of or along with oxygen evolving.
Sodium metal can be obtained by electrolysis from molten mixture of sodium chloride and calcium chloride in Down's cell. The metal can not be obtained by electrolysis from aqueous solution, because hydrogen will evolve instead.
If you use potassium hydroxide instead of sodium hydroxide, you would make potassium salts instead of sodium salts. For example, if you reacted potassium hydroxide with hydrochloric acid, you would produce potassium chloride.
No, sodium chloride (table salt) cannot be used to make soap instead of lye. Lye (sodium hydroxide or potassium hydroxide) is the essential ingredient needed to saponify fats and oils to make soap. Sodium chloride does not have the same chemical properties to facilitate the soap-making process.

If you are asking for the difference between the electrolysis of concentrated NaCl and aqueous NaCl, the water molecules in aqueous NaCl undergoes the Redox reactions rather than the sodium and chloride ions because the electric potential is higher. In concentrated NaCl, the chlorine atoms are oxidised instead.
Aqueous solutions of sodium chloride have a much lower conductivity compared to molten sodium chloride, which affects the efficiency of the electrolysis process. In molten form, sodium chloride can conduct electricity better as the ions are free to move, allowing for the electrolysis to occur more effectively.
when an aqueous solution is used, hydrogen gas is evolved at cathode, instead of depositing sodium metal.

When molten sodium chloride is electrolyzed, however, sodium is produced at the cathode.
When electricity is passed through an aqueous solution of sodium chloride (saltwater), a process called electrolysis occurs. The water molecules in the solution are split into hydrogen and oxygen gases at the cathode and anode, respectively, while the sodium and chloride ions in the solution migrate towards the oppositely charged electrodes. This process results in the production of hydrogen gas, chlorine gas, sodium hydroxide, and additional byproducts depending on the specific conditions.
Usually hydrogen will evolve from the cathode and oxygen from the anode, but if zinc is the anode, it may dissolve to produce zinc ions in the solution either instead of or along with oxygen evolving.
It would be predicted that it would smell like ammonia, but when performing the actual test myself I found no odor change. I would probably predict a possible pH change.
