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.

What valuable product are formed from the electrolysis of brine?
Chlorine gas and sodium hydroxide, which is why it's called the chlor-alkali process.
What is chlor-alkali process?
The chlor-alkali process is a method used to produce chlorine gas, sodium hydroxide (caustic soda), and hydrogen gas from brine (a solution of sodium chloride in water). The process involves the electrolysis of the brine solution in an electrolytic cell to break down the sodium chloride into its constituent elements. These products are widely used in various industries such as chemicals, food processing, and water treatment.
What is the purpose of using brine in soap manufacturing?
Brine is used in soap manufacturing as a salt solution that helps improve the hardness and quality of the soap bars. It also helps accelerate the saponification process, leading to faster soap production. Additionally, brine can enhance lather and cleansing properties of the soap.
How is chlorine gas commercially prepared?
Chlorine gas is commercially prepared by the electrolysis of brine (sodium chloride solution) in a process known as the chlor-alkali process. This method involves passing an electric current through brine to produce chlorine gas, sodium hydroxide, and hydrogen gas. The chlorine gas is then collected and used in various industrial applications, such as water treatment and chemical manufacturing.
What product is manufactured by electolysis in factorise?
Electrolysis in factories is commonly used to produce chlorine and sodium hydroxide (caustic soda) from brine (saltwater) through the chlor-alkali process. This process involves passing an electric current through the brine solution, resulting in the separation of chlorine gas at the anode and hydrogen gas at the cathode, while sodium hydroxide remains dissolved in the solution. These products are essential for various industrial applications, including water treatment, chemical manufacturing, and soap production.

Where can the element chlorine be obtained?
Chlorine can be obtained from saltwater sources such as brine wells or by electrolyzing sodium chloride (table salt) in a process called the chlor-alkali process. It is also produced as a byproduct of certain chemical reactions involving chlorine-containing compounds.
When electric current is passed through a strong solution of brine then what will happen?
When electric current is passed through a strong solution of brine (sodium chloride in water), electrolysis occurs. Chlorine gas is produced at the anode, sodium metal at the cathode, and sodium hydroxide remains in solution. This process is known as the chlor-alkali process.
How many chlor-alkali plants are there in the US?
There are approximately 52 chlor-alkali plants in the United States. These plants produce chlorine and caustic soda through the electrolysis of salt brine.
What human needs does the chlor-alkali industry serve?
Chlor-alkali industry provides us with sodium hydroxideand Chlorine gas. These two are produced by electrolysis (decomposition by electricity) of brine (saturated sodium chloride solution).
How do you prepare NaOH from sea water?
NaOH is scientifically known as sodium hydroxide, and commercially known as caustic soda. It is made from the electrolosis of a salt water solution called brine in a manufacturing facility known as a chlor-alkali plant. Sea water could obviously be used, but would be weaker in concentration than the commercially prepared brine.In any case, the brine flows in a trough over a running bed of liquid mercury. Carbon rods are immersed in the brine and act as electrodes to carry a strong electrical current through the brine solution. This results in the salt (sodium chloride - NaCl) breaking down and releasing chlorine gas (Cl2), with the Na then picking up the hydroxyl radical (OH-) to become NaOH.The reaction also produces a weak solution of sodium hypochlorite (NaOCl) a bleaching solution known commercially as Javex or Chlorox.
How is sodium hydroxide manufactured?
Sea water is a free and rich source of sodium chloride. Electrolyzing a sodium chloride solution is a popular method of manufacturing sodium hydroxide. The same method is used in industrial method, and another advantage is that the manufacturing of two other important substances, namely hydrogen and chlorine gases.
