Acetic acid dissociated to 1.20 % in its 0.01 M solution. What is the value of its dissociation constant?

Options

  1. A2.20 10⁻²
  2. B1.60 10⁻⁴
  3. C1.44 10⁻⁶
  4. D2.40 10⁻⁴

Correct answer

C. 1.44 10⁻⁶

Step-by-step solution

Percent dissociation =1.20 % Degree of dissociation ( )=0.012 For a weak monobasic acid, K _ a = ^2 c =(0.012)^2 0.01=1.44 10⁻⁶
