Redox Reactions And Electrochemistry Question 198
Question: In the following reaction, $ 3Br_2+6C{{O}^{2-}}_3+3H_2O \to 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 oxidised
Show Answer
Answer:
Correct Answer: D
Solution:
[d] $ 3\overset{0}{\mathop{B}},r_2+6CO_3^{2-}+3H_2O$ $\to 5\overset{-1}{\mathop{B}} r^{-}+\overset{+5}{\mathop{B}}rO^{-} _3+6HCO _{3.} $ in this reaction bromine is oxidized as well as reduced.
