I think it has something to do with the way chlorine,sodium hydroxide and hydrogen are formed.but i don"t know how to design the experiment

electrolysis of brine
Electrolysis of brine requires inert electrodes, such as platinum or graphite, to prevent the electrodes from reacting with the products of the electrolysis. Using inert electrodes ensures that the reactions at the electrodes are solely due to the electrolysis of the brine solution and do not introduce impurities or alter the chemical composition of the products.
Chloride is made from brine by electrolysis. Brine is a solution of sodium chloride in water, and when an electric current is passed through it, the sodium and chloride ions separate. The chloride ions are then collected to be used as a chemical product.

Chlorine is produced at the anode. Brine at the cathodeOxidation reaction: 2 Cl- --'anode'--> Cl2 + 2e-
By the sea where there is plenty of salt water. (Brine)
The pH of the solution after electrolysis of a brine solution will depend on the concentration of the resulting ions in the solution. The electrolysis of brine solution produces chlorine gas, hydrogen gas, and sodium hydroxide. The pH of the solution will increase due to the formation of sodium hydroxide, making it alkaline.
Electrolysing brine is economically important because it produces chlorine and caustic soda, which are key ingredients in the production of various products such as plastics, paper, and cleaning agents. These products have a wide range of industrial applications, making electrolysis of brine a crucial process for many industries.
The only one of the four that's "commonly refined by electrolysis" is brine, but whether it'll be refined by electrolysis or by just pouring it into a shallow container and allowing it to evaporate depends on the products you want to obtain.If you're trying to get sodium hydroxide, hydrogen and chlorine, electrolysis is the process for you. This is the Chloralkali process. If you want salt, evaporation is the way to go.
Mercury cell process: Electrolysis of brine (sodium chloride solution) using a mercury cathode. Membrane cell process: Electrolysis of brine through a membrane that selectively allows sodium ions to pass while blocking other ions. Diaphragm cell process: Electrolysis of brine separated by a porous diaphragm to prevent mixing of products and byproducts.
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.
That sounds like a good experiment to do.
