How chloride is made from brine?
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.
What happens when electricity is passed through brine?
Passing electricity through brine (saltwater solution) can result in the electrolysis of water, producing hydrogen gas at the cathode and chlorine gas at the anode. The sodium ions in the brine remain in solution. This process is used industrially to produce chlorine and sodium hydroxide.
Where is chlorine found or mined?
Chlorine is primarily found in the Earth's crust as the mineral halite (rock salt), which can be mined from underground salt deposits. It can also be extracted from seawater through a process called electrolysis. Additionally, chlorine is produced commercially through the electrolysis of brine (sodium chloride solution) or by the thermal decomposition of hydrochloric acid.
Why sulfuric acid added to water during electrolysis?
Sulfuric acid is added to water during electrolysis to increase the conductivity of the solution. This helps ions move freely in the solution and facilitates the electrolysis process by allowing the flow of electric current. It also helps in stabilizing the pH of the solution.
What electrode do brine and chlorine produce after electrolysis?
Chlorine is produced at the anode. Brine at the cathodeOxidation reaction: 2 Cl- --'anode'--> Cl2 + 2e-
Why do electrolysis of brine need inert electrodes?
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.

What is the pH of saurkraut?
the decrease of the pH in sauerkraut is due to the succession of lactic and acetic acid microorganisms that grow on the brine solution making it acidic.
Which component is reduced during the electrolysis of brine?
water
Where is the best place to carry out the electrolysis of brine on an industrial scale?
By the sea where there is plenty of salt water. (Brine)

3 methods used to produce chlorine?
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.
What is the process of manufacturing alkali from brine?
There are several processes, but the simplest is electrolysis with a diaphragm cell. Electricity is passed through the brine, hydrogen ions from the water are attracted to the cathode and discharged to form hydrogen gas. This results in a build up of hydroxide ions in the solution, effectively turning sodium chloride solution (brine) into sodium hydroxide solution (an alkali). You'll find this process in any standard chemistry text.
