Consider the change in oxidation state of Bromine corredponding to different emf values as shown in the diagram below :
.
The the species undergoing dispropprtionation is .

A

`BrO_(3)^(-)`

B

`BrO_(4)^(-)`

C

HBrO

D

`Br_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`E_("cell")^(@)` for the disproportionation of HBrO,
`E_("cell")^(@) = E_(HBrO)//(Br_(2))^(@) - E_(BrO_(3)^(-)//(HBrO)^(@)`
`=1.595 - 1.5`
`=0.095 V = +ve`
Hence, option ( c) is correct answer.
