Higher the reduction potential value, greater is the tendency to undergo reduction and stronger is the oxidising power. beginmatrix&BrO-4&>&IO-4&>&ClO-4 E°/V&1.74&&1.65&&1.19 endmatrix

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

Ion $Cl O_{4}^{-}$ $I O_{4}^{-}$ $B r O_{4}^{-}$

Reduction potential $E^{\circ} / V$ $E^{\circ} = 1.19 V$ $E^{\circ} = 1.65 V$ $E^{\circ} = 1.74 V$

$Cl O_{4}^{-} > I O_{4}^{-} > B r O_{4}^{-}$

$I O_{4}^{-} > B r O_{4}^{-} > Cl O_{4}^{-}$

$B r O_{4}^{-} > I O_{4}^{-} > Cl O_{4}^{-}$

$B r O_{4}^{-} > Cl O_{4}^{-} > I O_{4}^{-}$

Higher the reduction potential value, greater is the tendency to undergo reduction and stronger is the oxidising power.
$E^{\circ} / V B r O_{4}^{-} 1.74 > I O_{4}^{-} 1.65 > Cl O_{4}^{-} 1.19$
