Reduction potentials of some ions are given below. Arrange them in decreasing order of oxidising power.

Options

A. `ClO_(4)^(-)gt IO_(4)^(-) gt BrO_(4)^(-)`
B. `IO_(4)^(-) gt BrO_(4)^(-) gt ClO_(4)`
C. `BrO_(4)^(-)gt IO_(4)^(-) gt ClO_(4)^(-)`
D. `BrO_(4)^(-)gtClO_(4)^(-)gtIO_(4)^(-)`

Answer

C

Explanation

The higher the reduction prtential, the higher is its tendency to get reduced. Hence, the order of their oxidising power is :
`BrO_(4)^(-)gtIO_(4)^(-)gtClO_(4)^(-)`
