Question

For propanoic acid (HC3H5O2, Ka = 1.3 10-5), determine the concentration of the species present, the pH, and the percent dissociation of a 0.32 M solution.

I've gotten everything but %dissociation

How do I do that?

Answer 1

alright I think you are going to have to set up an ice table and the Ka expresion. and go through the process of finding the [H30}

Answer 2

\[\frac{[H_3O^+]}{.32 M}X100\]
