Which is the best decription of behaviour of bromine in the reaction given below ? H_(2)O + Br_(2) HBR + HOBr

Answer»

Only oxidised
Only reduced
Both oxidised and reduced
Only PROTON accepted

Solution :In the reaction.
`H_(2)O+overset(0)(B)r_(2) rarr HO overset(+1)(Br)+Hoverset(-1)(Br)`
The oxidation number of bromine INCREASES from 0 to +1 and decreases from 0 to -1, dut to this reason bromine is both oxidised as WELL as reduced in the above reaction.
