Percent Ionization

Question

The  of a monoprotic weak acid is  What is the percent ionization of a solution of this acid?

Answer 1

So, I think you have asked a similar question before. You should be able to do these questions by now. I’ll do this but you should figure out how to do these problems. They really aren’t that difficult.

Monoprotic acic is HA

HA ==> H⁺+ A^-

Ka = [H⁺][A^-]/[HA]

0.0063 = (x)(x) / 0.131-x

x² = -0.0063x + 0.00083

x = 0.026. (Please check the math)

% ionization = 0.026/0.131 (x100%) = 19.8%
