Sodium hydroxide is manufacture by the electrolysis of brine solution. The reaction by `-` products are `:`

A

`Cl_(2)` and `H_(2)`

B

`Cl_(2)` and `Na-Hg`

C

`Cl_(2)` and `NaCl`

D

`Cl_(2)` and `O_(2)`

Text Solution

Verified by Experts

The correct Answer is:
1
`NaCl("conc.")hArr Na^(+)+Cl^(-)" "," "H_(2)OhArr H^(+)+OH^(-)`
At cathode `:2H^(+)+2e^(-)rarrH_(2)uarr`
At anode `:2Cl^(-)rarrCl_(2)uarr+2e^(-)`
`Na^(+)+OH^(-)rarrNaOH`
