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.

The production of carbon dioxide is shown by bubbling the gas from the reaction through lime water (in tube at left). The lime water is saturated calcium hydroxide solution (Ca(OH)2) which reacts with carbon dioxide (CO2) to precipitate solid calcium carbonate (CaCO3). This turns the lime water cloudy from its initially clear state.
