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

Options

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

Correct answer

C. 0.1 M CH ₃ COOH

Step-by-step solution

Among the given, pH of 0.1 M CH ₃ COOH is not equal to one as CH ₃ COOH is a weak acid, thus does not ionise completely.
