QJEEM24Ch13e7: JEE Main 2024 Chemistry - Class 12 JEEM24Ch13e7 Solution: Reduction potential of ions are given below: ClO 4 − IO 4 − BrO …

Question

Verified Solution • 2025–26 Session moderate

Reduction potential of ions are given below:

$\begin{array}{ccc} {ClO}_{4}^{-} & {IO}_{4}^{-} & {BrO}_{4}^{-} \\ E^{\circ} = 1.19 V & E^{\circ} = 1.65 V & E^{\circ} = 1.74 V \end{array}$

The correct order of their oxidising power is :

Accepted Answer

Higher the value of $\oplus$ ve SRP (Std. reduction potential) more is tendency to undergo reduction, so better is oxidising power of reactant.

Hence, ox. Power:- ${BrO}_{4}^{-} > {IO}_{4}^{-} > {ClO}_{4}^{-}$
