Which one of the following is not a buffer solution?

Options

  1. A0.8 M H ₂ ~S +0.8 M KHS
  2. B2 M C ₆ H ₅ NH ₂+2 M C ₆ H ₅ NH ₃ ⁺ Br ⁻
  3. C3 M H ₂ CO ₃+3 M KHCO
  4. D0.05 M KClO ₄+0.05 M HClO ₄

Correct answer

D. 0.05 M KClO ₄+0.05 M HClO ₄

Step-by-step solution

Buffer solutions can be obtained by mixing a weak acid with its salt formed with a strong base or by mixing a weak base with its salt formed with a strong acid. As HClO ₄ is a strong acid, therefore equimolar mixture of HClO ₄ and its salt KClO ₄ is not a buffer solution.
