← ScienceWhich outcome occurs during sustained electrolysis of saturated sodium chloride solution?
A)Formation of chlorine gas and hydrogen✓
B)Precipitation of solid sodium chloride
C)Generation of ozone and sodium metal
D)Dissolution of the electrode material
💡 Explanation
During electrolysis of NaCl, oxidation and reduction occurs because ionic compounds dissociate into ions, with chloride ions oxidized to chlorine gas and water reduced to hydrogen gas releasing hydroxide ions. Therefore formation of chlorine and hydrogen results, rather than precipitation or metal production which require different electrochemical conditions.
