Calculate the percent dissociation of acetic acid (Ka = 1.8 x 10-5) in a solution containing 0.00973 M CH3COOH and 0.0124 M K(CH3COO). Report your answer to 2 significant figures.

Thanks!

1. Calculate (H^+) in the buffered solution. Then percent ionization is
%ion = [((H^+)/0.00973] *100

2. how would i calculate the H+?

3. The easiest way is to use the Henderson-Hasselbalch equation.
pH = pKa + log [(base)/(acid)]
