उत्तर
\[\ce{BrO^{-}_{4} > IO^{-}_{4} > ClO^{-}_{4}}\]
Explanation:
The ability of a substance to be decreased is known as its reduction potential. As the substance's reduction potential rises, so does its power to reduce. It signifies the chemical's oxidising power (the ability of the material to cause other substances to lose electrons, which is known as oxidising power) grows.
As a result, the oxidising power is listed in decreasing order.
