Calculate the degree of ionization of acetic acid in 0.01M Solution .Given Ka = 1.8 * 10^-5 at 298K.Calculate the Kb of its Conjugate Base ?
You're partially right, but need to be more specific. Solving for x like that gets you the concentration of dissociated acid from the 0.01M solution. You need to divide that by 0.01M to get the percent dissociation. The second half is correct.
Can you use Ostwalds law for this?
