Write the ionization expression for HAc.
HAc ==> H^+ + AC^-
now K = (H^+)(Ac^-)/(HAc)
Now if NaAc is added, that increases the Ac^- (the common ion effect), that shifts the equilibrium to the left. What happens to the H^+ and how does that affect the pH. By the way, this is how you make a buffer solution.
