At the anode, the oxidation of bromide ions (1.07 ) occurs because it has a higher (less negative) potential than the oxidation of water (1.23 ) or fluoride ions (2.87 ). The product of the oxidation of bromide ions is liquid bromine.
At the cathode, the reduction of silver ions (+0.80 ) occurs because it has a higher potential than the reduction of water (0.83 ) or sodium ions (2.71 ). The product of the reduction of silver ions is solid silver
