Question: In the conversion \(Br_{2} \rightarrow BrO_{3}^{-},\) the oxidation state of bromine changes from....

In the conversion Br2→BrO3−,Br_{2} \rightarrow BrO_{3}^{-}, the oxidation state of bromine changes from.

A

– 1 to – 1

B

0 to – 1

C

0 to + 5

D

0 to – 5

Answer

0 to + 5

Explanation

Solution

Br20→BrO3−+5\overset{0}{Br_{2}} \rightarrow \overset{+ 5}{BrO_{3}^{-}}, in this reaction oxidation state change from 0 to + 5.
