#### What is the balanced equation for aspirin precipitated

The influence of activity and water dissociation should not influence the result in any significant manner so I`ll ignore them. pKa is 13.5 so thats a Kb of 0.3162 so Kb=[K ][OH-]/[KOH] if OH- is x we have 0.3162=x^2/([KOH]-x) we known [OH-](and thus x) from the pH x=0.6198 so we can now find [KOH] for a pH of 13.76 which is 2.08mol/L so 0.1353mol for 65 mL, 0.1353 mol of KOH is 7.59g.
