| Abstract |
|
A series of experiments based on aspirin have been used in our high school chemistry laboratory. Experiments include (i) synthesis, purification, and characterization of aspirin by mp and TLC, (ii) percentage composition of a commercial aspirin tablet by titration, (iii) kinetics of the hydrolysis of aspirin to salicylic acid under various conditions, (iv) synthesis and characterization of copper(II) aspirinate and copper(II) salicylate, and (v) reaction of copper(II) aspirinate in aqueous solution.

| Supplement |
Synthetic and analytical procedures, Kinetics of Hydrolysis of ASA,
Determination of the Effect of pH on the Formation of an Iron-Salicyclic
Acid Complex, the Synthesis of Copper (II) Aspirinate and Salicylate, and
references are included.
