Chapter 13 #7a

The question asks to determine the pH and pOH of a solution that is 0.50 M NaHSO4 and .25 Na2SO4. What is the chemical equation for this reaction? If there are two steps, what are the two steps?

The chemical equation is HSO4- + H2O double arrows H3O+ +SO42-. You just use one equation for each part of this question and calculate the pH using the Henderson-Hasselbalch equation for the various concentrations of acid and conjugate base.

There is no ka or pka given, How are we supposed to go about the problem without that
