| Determining the melting point of aspirin • Firstly we turned on the melting point equipment; we referred to data tables for the actual value for the melting point of the aspirin. • Then we arranged the equipment to a point below the expected melting point we then noted that the rate of heating will influence the reading of the melting point. • Afterward we dipped the sealed capillary tube provided into the sample of our aspirin prepared until we got sufficient depth (about

Aspirin analysis Introduction Aspirin‚ which is also known as acetylsalicylic acid. C9H8O4 is the chemical format for Asprin. The chemical structure of aspirin: Aspirin is anti-inflammatory. Aspirin is prepared by chemical synthesis from salicylic acid‚ by acetylation with acetic anhydride. The fact that it is an acid allows us to quantify the amount of aspirin in a solution. We would do this by by using an acid-base titration. Sodium hydroxide (NaOH) will be used In this experiment as the

Today‚ aspirin is one of the most widely used medication on this Earth and has been since its popular breakout in the late 1890s. Long before we were born there was no such thing of a medication called aspirin. Instead‚ ancient people used willow leaves and bark from trees to help relieve oneself from pain and fevers. Aspirin as we come to know it in the form of an acetylsalicylic acid‚ was introduced to the world by Chemist Felix Hoffmann who was working at Bayer pharmaceutical company located in

1.0 Introduction The place of measurement is crucial in accounting. Measurement is vital to accountants for recording‚ summarising‚ reporting financial transactions and preparing financial statements that should indicate the true position of an entity. However‚ accounting measurement issues are seen to be problematic as many measurements are derived. According to Mary E. Barth (2007)‚ an analysis regarding the latest activities of the International Accounting Standard Board (IASB) have revealed

Synthesis of Aspirin and Tylenol Kyla Wykoff Abstract Aspirin and Tylenol were synthesized by means of crystallization‚ recrystallization‚ and melting point determination. Synthesis produced significantly high percent yields for aspirin‚ however‚ produced extremely low and impure percent yields for Tylenol. A second group was also used to compare results and errors‚ in which they too were also producing extremely low percent yields of Tylenol. Therefore‚ error was based on the specific protocol

Synthesis of Aspirin (Acetylsalicylic Acid) Abstract: This experiment is about the synthesis of aspirin under laboratory conditions. Aspirin is prepared by reacting salicylic acid and acetic anhydride; in the presence of sulfuric acid. After fully dissolving the salicylic acid with acetic anhydride‚ the solution is cooled and cold water is then added. Once the crystals form they are then filtered and left to dry out. There mass is measured and recorded then the yield is calculated. Introduction:

Abstract: The goal of this experiment was to synthesize aspirin. In this experiment aspirin‚ also known as acetylsalicylic acid‚ was synthesized from salicylic acid and acetic anhydride. In the reaction the hydroxyl group on the benzene ring in salicylic acid reacted with acetic anhydride to form an ester functional group. This method of forming acetylsalicylic acid is an esterification reaction. Since this esterification reaction is not spontaneous‚ sulfuric acid was used as a catalyst to initiate
