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.
