Which element is produced at the cathode during the electrolysis of brine in Nelson's cell?
Correct answer: A. Na
- A. Na
- B. H2
- C. O2
- D. Cl2
Explanation
The correct answer for the element produced at the cathode during the electrolysis of brine in a Nelson's cell is:(a) NaHere's why:Nelson's cell: is a type of diaphragm cell used for the electrolysis of brine (sodium chloride solution).Electrolysis: involves passing an electric current through the solution, causing the dissociation of molecules into ions.Cathode: is the negatively charged electrode where positive ions (cations) are attracted and reduced.Brine electrolysis:Sodium chloride (NaCl) dissociates into Na⁺ and Cl⁻ ions.At the cathode, Na⁺ ions gain electrons to become neutral sodium metal (Na) atoms.Chlorine gas (Cl2) is produced at the anode by the oxidation of chloride ions.Therefore, in a Nelson's cell, sodium metal is the element produced at the cathode due to the reduction of sodium ions.
