Answer» Na and `Br_(2)` Na and `O_(2)` `H_(2) Br_(2), NaOH` `H_(2)` and `O_(2)` Solution :`NaBr overset("ionises")rarrNa^(+)(aq)+Br^(-)(aq)` since the electrode potential of `H_(2)O(-0.83 V)` is HIGHER than that of `Na^(+)` (-2.71) therefore `H_(2)O` is reduced in preference to `Na^(+)` ions at anode `2 br^(-)(aq)RARR Br_(2)(g)+2E^(-)` thus `H_(2)` is liberated at the CATHODE `Br_(2)` at the anode and NaOH is left in the solution
