Bromine is both reduced and oxidized

Vedclass · Answer

(D) In the given reaction,the oxidation state of bromine $(Br_2)$ in the reactant side is $0$.When it changes to $BrO_3^-$,the oxidation state of bromine increases to $+5$,which indicates oxidation (loss of electrons).When it changes to $Br^-$,the oxidation state of bromine decreases to $-1$,which indicates reduction (gain of electrons).Since bromine undergoes both oxidation and reduction,this is a disproportionation reaction.Therefore,bromine is both reduced and oxidized.
