Reduction potentials of same ions are given below. Arrange them in decreasing order of oxidising power. {:("Ion",ClO_(4)^(-),IO_(4)^(-),BrO_(4)^(-)),("Reduction potential"E^(@)//V,E^(-)=1.19V,E^(-)=1.65V,E^(-)=1.74V):}

Answer»

`ClO_(4)^(–) GT IO_(4)^(–) gt BrO_(4)^(–)`
`IO_(4)^(-)gtBrO_(4)^(-)gtClO_(4)^(-)`
`BrO_(4)^(-)gtIO_(4)^(-)gtClO_(4)^(-)`
`BrO_(4)^(-)gtClO_(4)^(-)gtIO_(4)^(-)`
