Brine elctrolysis is where a solution of sodium chloride (common table salt) dissolved in water is broken down into chlorine gas, hydrogen gas, hydroxide ions and sodium ions by passing and elctrical curren through the solution. The chlorine gas will liberate at the cathode and hydogen at the anode, and the two ions produced will combine to form a solution of sodium hydroxide, a very strong alkali which has many applications. (The NaOH solution will be, when the reaction is complete, in place of the NaCl solution). Hope this is useful!!
Mercury is used as the cathode,and carbon in the form of graphite, is used as the anode.
electrolysis of brine
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.
It's an example of electrolysis. Not unwanted hair removal, but that does use the same process. Electrolysis is the process of breaking down compounds by running an electric current through them.
A compound that can be separated by electrolysis must be in the LIQUID state of matter.
Electrolysis is a chemical process where an electrolyte is chemically decomposed into its consituents by passing an direct electric current through it inside an electric cell.
By the electrolysis of brine.

water
By the sea where there is plenty of salt water. (Brine)
Chlorine is produced at the anode. Brine at the cathodeOxidation reaction: 2 Cl- --'anode'--> Cl2 + 2e-
it is because brine is an important source of two elements i.e. Sodium and Chlorine. Obtaining them is much easier by electrolysis then other methods.
Chlorine is a gas so it is not mined. It is manufactured by the electrolysis of a brine (salt) solution.

Chlorine gas and sodium hydroxide, which is why it's called the chlor-alkali process.
this is due to the fact that there is production of hydogen gas, chlorine gas and sodium hydroxide which has their individual characteristic importance
Slightly alkaline (from 7.1 to 8.5)
The effects will vary based on the amount of overpotential, the current density, the electrode materials used, and the concentration of the brine, but in general: - higher overpotential will increase the reaction rate - the brine will become warmer and thermodynamic efficiency decreases - side reactions are more likely to occur, such as electrode stripping and increased Cl2 production at anode
