12.55 a

Postby MichelleTran3I » Fri Dec 08, 2017 1:09 am

Calculate the pH, pOH, and percentage deprotonation of each of the following aqueous solutions: (a) 0.20 m CH3COOH(aq); (b) 0.20 m CCl3COOH(aq); (c) 0.20 m HCOOH(aq). (d) Explain any differences in pH on the basis of molecular structure.

How do you calculate Ka for part a when you are only given 0.2 M? The solutions manual states it as 1.8x10^-5. Thanks!

The Ka values are given in the tables 12.1 and 12.2
