Reduction potential of some ions are given below. Arrange them in decreasing order of oxidising power.
`{:("Ion",ClO_(4)^(-),IO_(4)^(-),BrO_(4)^(-)),("Reduction",E^(Theta),E^(Theta)=1.65V,E^(Theta)=1.74V),("potential "E^(Theta)//V,,,):}`

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)^(-) gt ClO_(4)^(-) gt IO_(4)^(-)`

Answer

A

Explanation

Higher the reduction potential higher is its tendency to get reduced. Hence, the order of oxidising power is:
`ClO_(4)^(-) gt IO_(4)^(-) gt BrO_(4)^(-)`.
