• # question_answer The products formed when as aqueous solution of NaBr is electrolysed in a cell having inert electrodes are A) $\operatorname{Na}\,and\,B{{r}_{2}}$ B)        $\operatorname{Na}\,\,and\,\,{{O}_{2}}$ C) ${{H}_{2}},\,B{{r}_{2}}\,and\,\,NaOH$           D) ${{\operatorname{H}}_{2}}\,and\,\,{{O}_{2}}$

At cathode ${{H}^{+}}$ reduces to ${{H}_{2}}$ and at anode $B{{r}^{-}}$ oxidises to$B{{r}_{2}}$, leaving NaOH in the solution.
