Titration- Analysis of Aspirin Tablets Objective: Determine the percentage of aspirin (acetylsalicylic acid) present in two different commercial tablets by titrating the solution with a base. Also determine whether the aspirin is a strong or weak acid according to the Bronsted- Lowry and Lewis theories and deduce the formula of the acid- base reaction. Independent Variable: The amount of base (NaOH) in moles that are needed to neutralize the solution. Dependent Variable: Percentage of aspirin (acetylsalicylic
