Redox Reactions And Electrochemistry Question 638
Question: In the reaction $ 3Br_2+6CO_3^{2-}+3H_2O\xrightarrow{{}} $ $ 5B{{r}^{-}}+BrO_3^{-}+6HCO_3^{-} $
Options:
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
Show Answer
Answer:
Correct Answer: D
Solution:
[d] $ 3Br_2+6CO_3^{2-}+3H_2O\to $ $ 5B{{r}^{-}}+BrO_3^{-}+6HCO_3^{-} $ O.N. of $ Br_2 $ changes from 0 to -1 and +5 hence it is reduced as well as oxidised.
