A. Calculate the percent ionization of a .600M solution of the monotropic acetyl

Question

A. Calculate the percent ionization of a .600M solution of the monotropic acetylsalicyclic acid. Ka=4.7*10^-5.
B. The pH of the gastric juice in the stomach of a certain individual is 1.00. After a few aspirin tablets have been swallowed, the concentration of the acetylsalicyclic acid in the stomach so 0.200M. Calculate the percent ionization in these conditions A.

Explanation / Answer

a)

ionisation % = (Ka/C)^1/2*100

             = (4.7*10^-5/0.6)^1/2 *100

             = 0.885%
