Question

Reduction potentials of some ions are given below. Arrange them in decreasing order of oxidising power.
Ion `" " CiO_(4)^(-) " " IO_(4)^(-) " " BrO_(4)^(-)`
Reduction `" " E^(Theta)=1.19 V " " E^(Theta)=1.65 V " " E^(Theta)=1.74`
potential `E^(Theta)//V`
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)^(-)IO_(4)^(-)`

Answer 1

Correct Answer - C
It is the correct decreasing order of oxidising power.
