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 happens at the anode and cathode in the electrolysis of brine?
In the electrolysis of brine (saltwater), at the anode, chloride ions (Cl⁻) are oxidized to form chlorine gas (Cl₂). At the cathode, water molecules are reduced to produce hydrogen gas (H₂) and hydroxide ions (OH⁻). This process results in the formation of chlorine gas at the anode and hydrogen gas at the cathode, with sodium hydroxide (NaOH) remaining in the solution.
Why is electrolysing brine economically important?
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.
How is electrolysis used to extract salt?
Electrolysis is used to extract salt, primarily sodium chloride (NaCl), by dissolving it in water to create a brine solution. When an electric current is passed through the brine, it causes the sodium ions to migrate to the cathode, where they are reduced to form sodium metal, while chlorine ions migrate to the anode, where they are oxidized to produce chlorine gas. This process not only allows for the extraction of sodium but also generates chlorine gas, which is a valuable byproduct. The resulting products can be further processed to obtain pure sodium and chlorine.
Why cathode steel used for production of brine?
Cathode steel is used for the production of brine because it is resistant to the corrosive effects of the brine solution. This helps to ensure the longevity and efficiency of the equipment used in the brine production process. Additionally, cathode steel is a suitable material for maintaining the purity of the brine solution during production.

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.
Why chloride ions are discharged at anode instead of hydroxide ions during the electrolysis of brine?
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.
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-
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)

After electrolysis of brine solution what is the pH of that solution?
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.
What are the Safety precautions observed during electrolysis of brine?
During electrolysis of brine, safety precautions include wearing protective goggles and gloves to prevent contact with the chemicals, ensuring good ventilation as hydrogen gas may be produced, and keeping the electrical setup dry to prevent electrocution hazards. Additionally, using proper tools and equipment, following manufacturer instructions, and having a fire extinguisher nearby are important safety measures.
What is the electrode at which chlorine is produced?
Chlorine gas is produced at the anode during the electrolysis of aqueous sodium chloride (brine) solution. At the anode, chloride ions are oxidized to form chlorine gas.

Which of these substances is commonly refined by electrolysis brine rust titanium water?
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.
