What is the reaction occuring at the anode in Down's process for the extraction of sodium?

Options

A. `4H rarr 2H_(2)O + O_(2) +4e`
B. `Na^(+) + e^(-) rarr Na`
C. `2Cl^(-) rarr Cl_(2) + 2e^(-)`
D. `NaOH rarr Na^(+) + OH^(-)`

Answer

(c )

Explanation

In Down's process, `Cl^(-)` is oxidised to `Cl_(2)` gas at anode.
`2CI^(-) rarr CI_(2) + 2e^(-)`
