The degree of ionization of 0.4 M acetic acid will be (K_ a =1.8 10⁻⁵ )

Options

  1. A6.71 10⁻³
  2. B1.6 10⁻³
  3. C0.4 1.8 10⁻⁵
  4. D1.8 10⁻⁵

Correct answer

A. 6.71 10⁻³

Step-by-step solution

For a weak acid (acetic acid), aligned K_ a &=C ² 1.8 10⁻⁵ &=0.4 ² &= 1.8 10⁻⁵ 0.4 &=6.71 10⁻³ aligned
