Which of the following represents the correct order for oxidising power of the given species ClO ₄⁻, BrO ₄⁻ and IO ₄⁻ ?

Options

  1. AClO ₄⁻> BrO ₄⁻>1 O ₄⁻
  2. BBrO ₄⁻> IO ₄⁻> ClO ₄⁻
  3. CIO ₄⁻> BrO ₄⁻> ClO ₄⁻
  4. DBrO ₄⁻> ClO ₄⁻>1 O ₄⁻

Correct answer

B. BrO ₄⁻> IO ₄⁻> ClO ₄⁻

Step-by-step solution

The reduction potential of the substance is the ability of the substance to be reduced. So, as the reduction potential increases, reducing ability of substance increases. It means oxidising power of the substance increases. The ability of the substance to make the other substance to lose the electrons increase. So, order of oxidising power is BrO ₄⁻> IO ₄⁻> ClO ₄⁻ .
