JEE Main 2024 Chemistry question
Reduction potential of ions are given below: ClO₄⁻ E° = 1.19 V, IO₄⁻ E° = 1.65 V, BrO₄⁻ E° = 1.74 V. The correct order of their oxidising power is
Answer: (B)
Solution
The higher the reduction potential, the stronger the oxidising power: BrO₄⁻ (1.74 V) > IO₄⁻ (1.65 V) > ClO₄⁻ (1.19 V).
