   You have to directly apply the ICE table method to your case.
   
   What is your HA? A^-?
   
   Basically it is about stoichiometry - from the dissociation reaction you can easily see that for each mole/molecule of A^- (H⁺) produced, one mole/molecule of HA is consumed. You just have to express concentrations of all three substances involved (HA, H⁺, A^-) in terms of one unknown - best approach is to use H⁺ as the unknown, as you are asked about pH.
