In the conversion fo Br2 to BrO3^(-) , ...

In the conversion fo ` Br_2` to BrO_3^(-)` , the oxidation state of `Br` changes from.

A

zero to `+5`

B

zero to `-3`

C

` + 1` to ` +5`

D

` +2` to ` +5`

Text Solution

Verified by Experts

The correct Answer is:
A
The change in oxidation number is as follows :
`overset (0) (B)r_(2) rarr overset (+5) (B)rO_3^(-)`
Let the oxidation number of Br in ` BrO_3^(-)` be `x`.
` x +3 (-2) =-1`
`x-6=-1`
` x=- +5`.
