    In the following reaction, \[3B{{r}_{2}}+6CO_{3}^{2-}+3{{H}_{2}}O\,\,=\,\,5B{{r}^{-}}+BrO_{3}^{-}\,\,+6HC{{O}_{3}}\]

    A) Bromine is oxidised and carbonate is reduced

    B) Bromine is reduced and water is oxidised 

    C) Bromine is neither reduced nor oxidised  

    D) Bromine is both reduced and oxidised    

    Correct Answer: D

    Solution :

    \[3{{\overset{0}{\mathop{Br}}\,}_{2}}\,+\,6CO_{3}^{2-}\,\,+\,\,3{{H}_{2}}O\,\,\to \,\,5\overset{-1}{\mathop{B{{r}^{-}}}}\,\] \[+\,BrO_{3}^{-}\,\,+\,\,6HC{{O}_{3}}\] In this reaction bromine is oxidised as well as reduced.
