Acetylsalicylic Acid (Aspirin) Questions
and Answers
overview of the experiment - answer using salicylic acid and acetic anhydride to
make acetylsalicylic acid (aspirin)

salicylic acid - answer starting material

acetic anhydride - answer starting material

acetylsalicylic acid - answer end product - aspirin

what kind of acid is used to protonate an O in acetic anhydride - answer phosphoric
acid

or

sulfuric acid, H3PO4
H-O-SO3H

also acts a catalyst!

what kind of reaction is this - answer exothermic

why do we add water during the reaction and not at the begining - answer if added at
the beginning it would hydrolyze the acetic anhydride and then the reaction could not
occur
^reason why we dont use HCl (80% water) and use sulfuric acid instead

add it in the middle to decompose extra acetic anhydride

**also its the crystallization solvent

hydrochloric acid is about as strong as sulfuric acid. why would HCl not be a satisfactory
catalyst in this reaction - answer HCl: 80% H2O, 20% HCl
sulfuric acid: 100% H2SO4

would hydrolyze the acetic anhydride, the reaction could occur

how do you account for the smell of vinegar when an old bottle of aspirin is opened -
answer moisture from the air will hydroyze the aspirin and break it down into salicylic
acid and acetic acid which is found in vinegar
