please explain thoroughly.

I need a methodology to answer both of these questions: 1) Confirm that Kyle's internet aspirin contains acetylsalicylic acid 2) Determine how much acetylsalicylic acid Kyle's internet aspirin contains EQUIPMENT AVAILABLE pH meters mortar & pestle burets & buret clamps ringstands stir plates & stir bars laboratory glassware . CHEMICALS AVAILABLE . . Phenolphthalein Methanol (used to dissolve the tablets) Aspirin tablets (containing acetylsalicylic acid) A sample of Kyle's internet aspirin Pure acetylsalicylic acid Standardized NaOH solution Benzophenone (in unknowns, for stabilization) . You will need to come up with the methodology to answer both of these questions. (using acid-base titration and back-titration(red-ox)] Note that the titrant (NaOH) is already standardized, so a KHP titration will not be necessary
