to synthesise acetylsalicylic acid (aspirin) by creating a reaction between acetic anhydride and salicylic acid. This was be accomplished through the use of recrystallization. Acetic anhydride and salicylic acid are mixed together‚ and then acidified by the addition of a few drops of concentrated sulfuric acid‚ which catalyzed the reaction. The percent yield is calculated to determine the effectiveness of the reaction in preparing the desired product (aspirin). The limiting reactant of the equation

Chewable aspirin can be chewed‚ crushed or swallowed whole but after being consumed the consumer should drink full glass of water. There are many uses for Aspirin. Prescription Aspirin is used to relieve symptoms of rheumatoid arthritis‚ arthritis caused by the swelling of the lining of joints‚ osteoarthritis‚ arthritis caused by breakdown of lining of joints‚ systemic lupus erythematosus‚ the immune system attacks joints and organs‚ and can cause pain/swelling. Nonprescription Aspirin is commonly

Food has become easier to prepare. Has this change improved the way people live? Use specific reasons and examples to support your answer. Of course‚ nowadays food has become more easier to prepare. Think about microwave-ovens‚ mixture‚ grinding machine‚ rice-cooker‚pressure cooker‚I think you already got the answer‚ right? In my point of view‚ the improvement of food preparing has obviously changed our lifestyle in a better way. These days‚ people need not use effort‚ every things are kept in

CHEM%2315%Fall%2014% Creating useful and beautiful molecules using synthetic organic chemistry – Synthesis of Aspirin and Indigo INTRODUCTION Aspirin Salicylic acid occurs naturally in the bark of willow trees. Prior to the 1800’s‚ willow bark was often brewed into a tea‚ or chewed to relieve pain. While the salicylic acid is effective at reducing pain it was found to irritate the lining of the stomach. It was mostly by chance that on August 10‚ 1897 Felix Hoffmann‚ a German chemist who obtained

Also‚ tie back long hair to prevent any accidental fire‚ and be familiar with the location of the fire extinguisher. Discussion The synthesis of aspirin demonstrated here demonstrates several relevant suggestions that should be considered in the synthesis of a substance. Firstly‚ the recrystallization of a product should be performed if possible and relevant. In most reactions‚ the amount of product
