The dissociation constant of a weak monobasic acid is 3.2 10⁻⁴ . Calculate the degree of dissociation in its 0.04 M solution.

Options

  1. A0.0128
  2. B0.0151
  3. C0.078
  4. D0.089

Correct answer

D. 0.089

Step-by-step solution

K _ a =3.2 10⁻⁴ ; c =0.04 M For a monobasic acid, = K_a c = 3.2 10⁻⁴ 0.04 = 8 10⁻³ =0.089
