Experiment # 3 Acetylsalicylic Acid Introduction: The purpose of this experiment is to create and isolate pure acetylsalicylic acid from the substances salicylic acid and acetic anhydride. Then one will find the melting point to determine purity. Procedure: Make a hot bath. Weigh some salicylic acid and place in conical vial. Add .480mL of acetic anhydride and a drop of concentrated phosphoric acid. Drop in a magnetic spin vane and attach air condenser to vial. Partially submerge it in

Laboratory exercise 3 : Quantitative analysis of vitamin C contained in a fruit juice Aim: To investigate the amount of vitamin C found in all kinds of fruit juice Introduction : Vitamin C is an antioxidant‚ along with vitamin E‚ beta-carotene‚ and many other plant-based nutrients. Antioxidants block some of the damage caused by free radicals‚ substances that damage DNA. The build-up of free radicals over time may contribute to the aging process and the development of health conditions such as
