Main reaction sequence including side reaction products: 2. 3 Sentence Summary of the Experiment: The OH group on the benzene ring in salicyclic acid reacts with acetic anhydride to form an ester functional group. Thus the formation of acetylsalicyclic acid (aspirin) is referred to as an esterification reaction‚ which requires the presence of H+ (H2SO4 in our case). The technique used to purify the aspirin content is called

Abstract- Expirement 1: Precision‚ Accuracy‚ and Density Measurements This experience is intended to introduce the proper use of the most used laboratory equipments and glasswear that is come upon in the lab. As well‚ to determine the mass‚ volume and density of water by using various types of measuring glasswear‚ such as beakers‚ graduated cylinder‚ pipet‚ etc... The measurement of the density of water will determine the precision and accuracy of these measuring glasswear. Also‚ there will be a
