An experiment is described that is suitable for the early portion of the laboratory in a general chemistry course and integrates organic examples. Excess anhydride reacts with water produced in esterification, which shifts the Acetic anhydride reacts with Salicylic acid to yield the ester (aspirin). Over the course of the first semester and the beginning of the second, our general chemistry students synthesize two organic substances (aspirin and methyl orange) and two inorganic substances (alum and potassium ferrioxalate). The mechanism for this synthesis provides examples of three major classes of chemical reactions: hydrolysis, condensation, and proton transfer.
