ANALYSIS OF ASPIRIN: SPECTROPHOTOMETRY The purpose of this experiment is to evaluate the percent aspirin on a commercial aspirin tablet using an instrumental method‚ spectrophotometry. In a spectrophotometer‚ light from a strong lamp passes through a monochromator‚ which breaks the light into its component colors using a grating‚ then uses mirrors and slits to direct a light beam of the desired wavelength through the sample compartment‚ where you place a tube (cuvette) of solution. A detector

What is the more formal chemical name for aspirin? Acetylsalicylic acid 2. Using your data from Experiment 2‚ how can you be sure you synthesized aspirin? By using the colors as a guide‚ we can compare the Acetylsalicylic acid + 8 mL FeCl3 to the Aspirin Crystals from Experiment 1 + 8 mL FeCl3 in order to see if it synthesized. 3. Would you say that your synthesized aspirin is relatively pure? How can you tell? One way that the purity of aspirin can be judged is by it’s color as pure acetylsalicylic
