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

In the conversion of Br2Br_{2}to BrO3−,BrO_{3}^{-}, the oxidation state of Br changes from.

A

+1 to +5

B

0 to -3

C
  • 2 to 5
D

0 to +5

Answer

0 to +5

Explanation

Solution

: Br2→BrO3−Br_{2} \rightarrow BrO_{3}^{-}

For Br2Br_{2}oxidation number = 0

For BrO3−BrO_{3}^{-} oxidation number, x+(−6)=−1⇒x=+5x + ( - 6) = - 1 \Rightarrow x = + 5
