A) bromine is oxidised and carbonate is reduced.
B) bromine is reduced and water is oxidized
C) bromine is neither reduced nor oxidized
D) bromine is both reduced and oxidized
Correct Answer: D
Solution :
[d] \[3B{{r}_{2}}+6CO_{3}^{2-}+3{{H}_{2}}O\to \] \[5B{{r}^{-}}+BrO_{3}^{-}+6HCO_{3}^{-}\] O.N. of \[B{{r}_{2}}\] changes from 0 to -1 and +5 hence it is reduced as well as oxidised.
