Hello there!
In this case, when considering weak acids which have an associated percent dissociation, we first need to set up the ionization reaction and the equilibrium expression:
Now, by introducing x as the reaction extent which also represents the concentration of both H+ and A-, we have:
Thus, it is possible to find x given the pH as shown below:
So that we can calculate the initial concentration of the acid:
Therefore, the percent dissociation turns out to be:
