Which is the best description of the behaviour of bromine in the reaction given below
`H_(2)O+Br_(2) rarr HOBr+HBr`

A

Oxidised only

B

Reduced only

C

Proton acceptor only

D

Both oxidised and reduced

Text Solution

Verified by Experts

The correct Answer is:
D
`H_(2)O+underset(0)(Br_(2)) rarr underset(+1)(HOBr)+underset(-1)(HBr)`
In the above reaction the oxidation number of `Br_(2)` increases from zero (in `Br_(2)`) to `+1` (in `HOBr`) and decreases from zero `(Br_(3))` to `-1` (in `HBr`). Thus `Br_(2)` is oxidised as well as as reduced and hence it is a redox reaction.
