← ScienceWhich consequence occurs when applying high voltage across powdered NaCl?
A)Cathode sputtering of sodium appears✓
B)Decomposition generates chlorine gas
C)Crystal lattice compression increases
D)Ohmic resistance behavior decreases
💡 Explanation
Cathode sputtering deposits sodium because **ionic conduction** allows Na+ ions to migrate towards the cathode where they are reduced and deposited, rather than chlorine evolution; this will occur under aqueous solution conditions because of electrolysis.
