The overall reaction taking place at anode during electrolysis of fused sodium chloride using suitable electrode is

Options

A. Oxidation of Chlorineions
B. Reduction of sodium ions
C. Reductions of chlorine
D. Oxidation of sodium atoms

Answer

A

Explanation

Electrolysis of fused NaCl
`NaCl to Na^(+) + Cl^(-)`
At cathode `(-Ve)`
`2Na + 2e^(-) to 2Na` (Reduction)
At anode `(+Ve)`:
`2Cl^(-) to Cl_(2) + 2e^(-)` (Oxidation)
