Not what you're looking for?
Hey there. I am having trouble with this question.
Calculate the percent ionization of propionic acid (C2H5COOH) in solutions of each of the following concentrations:
a) 0.250 M
b) 0.0800 M
c) 0.0200 M
** Ka = 1.3 x 10 ^ -5
Could you please show the work. And no power points please.
Thanks in advance!
