Synthesis of Aspirin Lab Report - Academicscope.

Experiment 11 Synthesis and Analysis of Aspirin. like sulfuric acid or phosphoric acid, is used to speed up the process. Part I: Synthesis of Aspirin Caution! The preparation of aspirin involves the use of two very hazardous materials - concentrated sulfuric. to calculate the theoretical yield of aspirin. Record the weigh on the report.

Determination of Aspirin using Back Titration This experiment is designed to illustrate techniques used in a typical indirect or back titration. You will use the NaOH you standardized last week to back titrate an aspirin solution and determine the concentration of aspirin in a typical analgesic tablet. You will be graded on your accuracy.

Aspirin is an orally administered non-steroidal antiinflammatory agent. Acetylsalicylic acid binds to and acetylates serine residues in cyclooxygenases, resulting in decreased synthesis of prostaglandin, platelet aggregation, and inflammation. This agent exhibits analgesic, antipyretic, and anticoagulant properties.

PREPARATION OF ASPIRIN EXPERIMENT 5 INTRODUCTION. Since, in this experiment, we start with a white solid and end up with a white solid, one may wonder whether or not any reaction has taken place at all. An excellent way to check. Lab report, hand in within 24 hours. 10 QUESTIONS 1. Conclude on the purity of your aspirin.

The humidity of the lab should be kept at a minimum, as acetic anhydride, a reactant in the synthesis of aspirin, tends to react with water vapour to form acetic acid. Phosphoric acid can be used instead of sulfuric acid if desired to obtain a higher yield, as sulfuric acid reacts more readily with the organic molecules involved in the reaction than phosphoric acid.

Lab Report. Preparation of Aspirin Lab Report. Introduction: The purpose of this experiment was to make aspirin via esterification, and to determine the percent yield we as a lab group made. Aspirin is an organic ester. An ester is a compound that is formed when an acid reacts with an alcohol,-OH group.

Abstract This report presents the synthesis of Aspirin (acetylsalicylic acid), as the product of the reaction of salicylic acid with ethanoic anhydride under acidic conditions. Aspirin was purified through recrystallisation by vacuum filtration, followed by desiccation of the Aspirin crystal over silica gel.

Title: Aspirin Tests Purpose: The purpose of this experiment was todetremine if the sample of aspirin contained phenol, starch, acid, and an ester Experimental: The experimental process involved determining the presence of these substances in the sample of aspirin provided.

Below is a lab report format that you can use if you do not know what to write or when you need to explain what is contained in various sections of the report. The title explains what you did. It should be short (target is ten words or less) and explain the main points of experiments and investigations.
