pH value of which one of the following is not equal to one?

Options

  1. A0.1 M CH ₃ COOH
  2. B0.1 M HNO ₃
  3. C0.05 M H ₂ SO ₄
  4. D50 ~cm ³ 0.4 M HCl +50 ~cm ³ 0.2 M NaOH

Correct answer

A. 0.1 M CH ₃ COOH

Step-by-step solution

0.1 M CH ₃ COOH is not completely dissociated. Therefore, pH will not be one.
