Preparation and melting point of Aspirin Aspirin is a painkilling drug and is produced worldwide to reduce and stop pain. Aspirin is made up of ehtanoylation of 2-hydroxbenzenecarboxylic acid in a presence of phosphoric acid. AIM: The aim of the experiment is to prepare and produce aspirin as pure as possible. I will do this threw preparing the aspirin and purifying the product threw recrystallization. I will then obtain a melting point of my product to get an estimate of its purity. By the end

I. INTRODUCTION A. Background of study Candy-coated sweets come in different colors and sometimes even vary in flavor in association with the colors. These colors provide a creative display for children to easily get attracted to the particular treat‚ leaving those tinted marks on their mouths and a happy‚ satisfied grin on their faces. The reason for conducting the research is to know how the colors of our favorite candy-coated sugary rewards came to be and that method of knowing is what we

Chromatography is divided into several types. Column Chromatography uses a powder adsorbent placed in a vertical glass column as its stationary phase and its solvent as the mobile phase. The mixture is distributed as the solvent moves down the column. Thin Layer Chromatography‚ or TLC‚ also uses a powder absorbent which is fixed to a metal‚ plastic or glass plate as its stationary phase. The mixture to be analyzed is placed near the bottom of the plate and it is then submerged to a specific amount of

Person Vs Self and Person Vs Person which is what i will be writing about. Do you think people should ever be allowed to climb everest again? I will be talking about the two books Time Of The Wolves and Into Thin Air. The people that had the most situations in the two stories were Rob from Into Thin Air and Alma and Sarah from Time Of The Wolves. In the short stories and books we have read there have been a lot of Person vs Self situations. One of the good one that had a good example of Person vs

described below. Chromatography is partially characterized by the medium on which the separation occurs. This medium is commonly identified as the “stationary phase”. Stationary phases that are typically used include paper (as in this experiment)‚ thin plates coated with silica gel or alumina‚ or columns packed with the same substances. The “mobile phase” is the medium that accompanies the analyzed substance as it moves through the stationary phase. Both liquids and gases can be used as mobile phases

Medicine Analysis – Synthesising Aspirin results After recrystallisation differences between the crude and purified aspirin were noted. The impure (crude) aspirin was powered and fluffy with small clumps and was slightly yellow in colour whereas the pure aspirin has a less fluffy crystalline powder and was whiter. This showed distinct differences in the two substances but similarities were also apparent showing aspirin‚ in some level‚ was created. Before recrystallisation the crude aspirin could
