Fittoniya [83]

Answer:

At anode - {Br_2}_{(l)}

At cathode - {H_2}_{(g)}

Explanation:

Electrolysis of NaBr:

Water will exist as:

H_2O\rightleftharpoons H^++OH^-

The salt, NaBr will dissociate as:

NaBr\rightarrow Na^++Br^-

At the anode, oxidation takes place, as shown below.

{Br^-}_{(aq)}\rightarrow {Br_2}_{(l)}+2e^-

At the cathode, reduction takes place, as shown below.

2{H^+}_{(aq)}+2e^-\rightarrow {H_2}_{(g)}
