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

Answer»

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

Solution :Greater the SRPvalue of spices, HIGHER will beits oxidising power . Hence , on the basis of the reductionpotenial of IONS, the DECREASING orderof oxidisingpoweris `BrO_(4)^(-) gtClO_(-)^(4)gt lO_(4)^(-)`.
