Restate the paragraph. The main objective of the laboratory activity was to make aspirin also known as acetylsalicylic acid in its scientific name. It was successfully done as aspirin was synthesized using the combination of salicylic acid and acetic anhydride. In this reaction, salicylic acid's hydroxyl group on the benzene ring interacted with acetic anhydride to generate an ester functional group. This is an esterification reaction that produces acetylsalicylic acid. Sulfuric acid was utilized as a catalyst to start the esterification reaction. Some unreacted acetic anhydride and salicylic acid, as well as sulfuric acid, aspirin, and acetic acid, remained in the solution after the reaction was completed. The process of crystallization was used to obtain pure crystals of a substance from an impure mixture. Upon completion of the lab, analysis, and calculations, , it is evident that the synthesis of aspirin is possible using these methods but that the yield will be relatively low
