In the reaction
`3Br_(2)+6CO_(3)^(2-)+3H_(2)Orarr5Br^(ө)+BrO_(3)^(ө)+6HCO_(3)^(ө)`

Options

A. Bromine is oxidised and carbonate is reduced
B. Bromine is reduced and water is oxidised
C. Bromine is neither reduced not oxidised
D. Bromine is both reduced and oxidised

Answer

D

Explanation

O.N of Br increases from 0 in `Br_(2)` to +5 in `BrO_(3)^(-)` ion and O.N of Br also decreases from 0 in `Br_(2)` to -1 in `Br^(-)` ion.
