Where does chlorine form in an electrolytic cell during the electrolysis of molten Na Cl?
Chlorine is released as a gas (diatomic molecule Cl2).
How do you prepare 50 ppm Na from Na-Cl?
Sodium is separated from sodium chloride by electrolysis.
Why do you use molten NaCl in electrolysis instead of an aqueous solution of NaCl?
Molten NaCl is preferred over an aqueous solution of NaCl in electrolysis because in the molten state, NaCl dissociates into Na+ and Cl- ions without the presence of water molecules, allowing for direct electron transfer at the electrodes. In an aqueous solution, water molecules also undergo electrolysis, leading to the production of hydrogen gas and oxygen gas, which can interfere with the desired reactions involving Na+ and Cl- ions. Additionally, the high melting point of NaCl ensures that it remains in the molten state during the electrolysis process, providing a stable environment for the reactions to occur.
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.
What component is reduced during the electrolysis of brine?
During the electrolysis of brine, chlorine ions (Cl⁻) are reduced at the anode, leading to the formation of chlorine gas (Cl₂). Meanwhile, water (H₂O) is oxidized at the anode, producing oxygen gas (O₂) and hydrogen ions (H⁺). At the cathode, hydrogen ions are reduced to form hydrogen gas (H₂). Thus, the primary component reduced in this process is the chlorine ion.

Can Na be extracted from the electrolysis of its aqueous solution of Na-Cl?
Yes, sodium (Na) can be extracted from the electrolysis of its aqueous solution of sodium chloride (NaCl). During electrolysis, sodium ions are reduced at the cathode to form elemental sodium. Meanwhile, chloride ions are oxidized at the anode to produce chlorine gas.

Which condition is most favorable for the cell if the solution is 0 Na Cl 0.5 Na Cl 0.9 Na Cl and 2 Na Cl and why?
The most favorable condition for the cell is 0.9 NaCl, as it is isotonic with typical mammalian cells. In an isotonic solution, the concentration of solutes (NaCl) is equal inside and outside the cell, preventing water from moving in or out and thus maintaining cell shape and function. Solutions with lower (0 NaCl) or higher concentrations (0.5 NaCl and 2 NaCl) could lead to cell swelling or shrinkage, respectively, which can disrupt cellular processes.
What are chlorine ions?
Chlorine ions are atoms of chlorine that have gained one electron, giving them a negative charge. This makes them anionic, meaning they are attracted to positively charged ions or molecules. Chlorine ions play important roles in processes such as water treatment and electrolysis.
