OF ASPIRIN Aspirin in general is a safe drug but the ability to prevent blood clots is connected to some side effects. Aspirin can cause firstly stomach irritation. That’s means aspirin can irritate your stomach which has as a result pain‚ nausea‚ vomiting or hearburn. Sometimes can have other symptoms like bleeding‚ holes in stomach or intestines. In order to minimize these problems it should be better to have a full stomach. Also another problem that comes from aspirin can

Abstract For the amount of aspirin in a commercial tablet to be determined‚ different solutions of acetylsalicylic acid mixed with NaOH were created at different concentrations. All the different solutions were then analysed using Novaspec photometer‚ which allowed for a graph to be created and a line of best fit to be made. The amount of aspirin in a commercial tablet was found to be 350mg. Introduction The molecular formula for aspirin‚ also known as acetylsalicylic acid‚ is C9H8O4. It is most

Reshmi Nair Title: Determination of Aspirin through back titration. Aim: To determine the concentration of Aspirin in a tablet using NaOH and Hcl. Research Question: What is the concentration of Aspirin in a normal tablet? Background: Aspirin is the general name for acetylsalicylic acid (ASA); it is also the trademark of the drug produced by Bayer in Germany. In eighty countries‚ aspirin is a registered trademark‚ but in other places the term aspirin refers to ASA by itself or as an ingredient

aspirin Intro- Aspirin is known as a pain reliever for muscle ache‚ head ache and can prevent heart attacks as well as blood clots‚ and many more things that it can help with. Aspirin is known as Acetylsalicylic acid (ASA) is a Salicylate. Salicylates are organic acids from plants that people for hundreds of years have been used for pain reducing. Salicylic acid irritates the stomach when consumed so German scientist Felix Hoffman suggested ASA as an alternative. Aspirin is made when Acetic Anhydride

Aspirin or acetylsalicylate acid is a compound that is widely used in medicine. The use of aspirin in medicine began long before the active reagent was removed from its natural source. The first documented use of aspirin was found in the writings of Hippocrates‚ the so called father of medicine. Hippocrates prescribed that willow bark could be used to remedy a wide range of conditions such as pain‚ fever and inflammation. Scientists began to seek to extract the active compound from willow tree bark

The Synthesis of Organic Aspirin ABSTRACT: The purpose of this experiment was to find out how a reaction undergoes for a globally known painkiller called aspirin‚ and to become familiar with achieving successful yields. Aspirin is synthesized from salicylic acid and acetic anhydride. Those two chemicals are mixed together along with sulfuric acid to form a crude solid. Filtration is used separate the impurities from the crude aspirin. To get purified aspirin‚ the precipitate was heated until all

Aspirin were used to relieve pain‚ inflammation‚ and fever. Aspirin were made using a combination of salicylic acid and acetic anhydride.The goal of this experiment was to determined the purity of aspirin using different methods. These methods included‚ reacting salicylic acid with FeCl3‚ finding its melting points‚ and by doing Thin-layer chromatography. When you reacted salicylic acid with FeCl3‚ changes in color will occur. Pure Aspirin has a melting point around 135°C and a pure salicylic acid

to synthesise pure aspirin using chemical tests such as esterification and recrystallization independently and to also find out the melting point range of aspirin using melting point determination. INTRODUCTION Aspirin‚ which is also known as acetylsalicylic acid‚ is one of the commonly used and widely found in any drugstore or pharmacy. Its properties make aspirin a well-rounded drug that reduces inflammation and fever and also relieves pain. The active ingredient in aspirin was found to be salicylic

History Of Aspirin Aspirin is one of the most commonly used drugs in the world.. For centuries people throughout the world. Aspirin was discovered about 3500 years ago. A collection of 877 medicinal recipes‚ The Ebers papyrus‚ before Christ‚ from the middle of the second millennium had been bought during the last century from an Egyptian street vendor by Georg Ebers‚ a German Egyptologist Georg.
