During electrolysis of aqueous solution of NaCI in Castner Kellner cell, the gas(es) produced are

Options

A. `CI_(2)`
B. `O_(2)`
C. `H_(2)`
D. `HCI`

Answer

A, C

Explanation

`NaCI rarr Na^(o+)+CI^(Θ)`
`H_(2)O` `H^(o+)+overset(Θ)OH`
At anode: `2CI^(Θ)rarr CI_(2)(g)+2e^(Θ)`
At cathode: `2H^(o+)+2e^(Θ)rarr H_(2)uarr`
