What is produced at each electrode in the electrolysis of nabr (aq) ?

The product at each electrode in the electrolysis of NaBr is as follows

At the anode is bromine

that is Br^ - (aq) = Br2 (aq) + 2e-

at the catode is sodium

that is Na^ + (aq) + 2e - = Na (s)

Bromine is produced at the anode since the standard potential of bromide oxidation is less positive than that of oxidation of water.
