Chlorine is produced at the anode. Brine at the cathode
Oxidation reaction: 2 Cl- --'anode'--> Cl2 + 2e-

Where is chlorine found or mined?
Chlorine is a gas so it is not mined. It is manufactured by the electrolysis of a brine (salt) solution.
How chloride is made from brine?
By the electrolysis of brine.
What is the effect of overpotential of hydrogen evolution in electrolysis of brine?
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
Why is the electrolysis of brine so important?
this is due to the fact that there is production of hydogen gas, chlorine gas and sodium hydroxide which has their individual characteristic importance
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).
Where is chlorine found or mined?
Chlorine is a gas so it is not mined. It is manufactured by the electrolysis of a brine (salt) solution.
Why is electrolysing brine economically important?
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.
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.
How chloride is made from brine?
By the electrolysis of brine.

What are the products of electrolysis brine solution?
Iron hydroxide (Fe(OH)2), Chlorine and Hydrogen.
What is the chloralkali industry?
electrolysis of brine
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.
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)
When electrolysis occurs in salt water chlorine and hydrogen are given off what happens to the sodium and oxygen?
The electrolysis of brine (salt solution) involves the breakdown of sodium chloride and water into its basic ionic components: sodium, hydrogen, chlorine and hydroxide ions. The hydrogen and sodium are both positively charged ions, and are attracted towards the negatively charged electrode, where the least reactive of the two ions - hydrogen - gains an electron to become an uncharged hydrogen atom. Sodium is more reactive, so it remains in the electrolysis chamber (sometimes called a diaphragm cell) as an Na+ ion. The chloride and hydroxide ions are negatively charged, so they are attracted to the anode, where the chloride is liberated as a chlorine molecule, because it is the least reactive of the two anions. The hydroxide remains in the container as an OH- ion. The chlorine is used to sterilise swimming pools and to make PVC plastics. The hydrogen is used in the process of making margarine. Meanwhile the sodium and the hydroxide ions join together to form sodium hydroxide, which is a widely used bleach. It is also used in the manufacture of paper and soap. The equation for the electrolysis of brine is: 2NaCl + 2H2O --------> Cl2 + H2 + NaOH
