`2Cl^(-)(aq)+2H_(2)Orarr2OH^(-)(aq)+H_(2)(g)+Cl_(2)(g)`
`62 %` efficient 25 A electricity is passed through 20L 20 % NaCl solution . ( i ) Write the electrode reactions ( ii ) How much time will it take to produce 1 kg `Cl_(2)` ( iii ) What will be the molarity at that time with respect to `OH^(-)` ? ( suppose no volume change occurs during electrolysis )
