What % of acetylsalicylic acid dissociates to make H3O+1 ions in water? Compare aspirin dissociation to acids like KHP and HCl. You will need to do a little bit of research and look into the acid dissociation constant, abbreviated by the symbol Ka. For context and clarity, you will want to define acid/base strength and acid dissociation constant.

II. Digestion of Acetylsalicylic acid(standard and tablet) with NaOH . Digestion of Acetylsalicylic Acid Standard to Prepare Stock Solution: Obtain ca. 0.1 g dried acetylsalicylic acid (MM = 180.16 g/mol), accurately weighed, and quantitatively transfer to a 125-ml Erlenmeyer flask. Add 5 ml 1.0 M NaOH and heat mixture to boiling on a hot plate. This will hydrolyze the acetylsalicylic acid to sodium salicylate. If necessary, rinse down the walls of the Erlenmeyer with DI water to ensure complete hydrolysis...
