Redox Reactions And Electrochemistry Ques 498

Question: In the following reaction, $ 3Br_2+6CO_3^{2-}+3H_2O=5B{{r}^{-}}+BrO_3^{-}+6HCO_3 $ [MP PMT 1994, 95]

Options:

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 oxidized

Show Answer

Answer:

Correct Answer: D

Solution:

$ \overset{0}{\mathop{3Br_2}},+6CO_3^{2-}+3H_2O\to \overset{-1}{\mathop{5B{{r}^{-}}}},+\overset{+5}{\mathop{BrO_3^{-}}},+6HCO_3 $ . In this reaction bromine is oxidised as well as reduced.
