Why Na cannot be obtained by the electrolysis of aqueous `NaCl` solution ?

Text Solution

AI Generated Solution

To understand why sodium (Na) cannot be obtained by the electrolysis of aqueous NaCl solution, we need to analyze the electrolysis process and the relevant reduction potentials of the ions involved. ### Step-by-Step Solution: 1. **Identify the ions in aqueous NaCl solution**: - In an aqueous solution of NaCl, the dissociated ions are Na⁺ (sodium ions) and Cl⁻ (chloride ions). Additionally, water (H₂O) dissociates into H⁺ (hydrogen ions) and OH⁻ (hydroxide ions). - Therefore, the ions present in the solution are Na⁺, Cl⁻, H⁺, and OH⁻. ...
