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

anesthetic‚ also spelled anaesthetic ‚ any agent that produces a local or general loss of sensation‚ including pain. Anesthetics achieve this effect by acting on the brain or peripheral nervous system to suppress responses to sensory stimulation. The unresponsive state thus induced is known as anesthesia n anxiolytic (also antipanic or antianxiety agent[1]) is a drug used for the treatment of anxiety‚ and its related psychological and physical symptoms. Anxiolytics have been shown to be useful

Formal Report no. 1 Synthesis of Aspirin Chemical Principles Aspirin is most widely sold over-the-counter drug. It has the ability to reduce fever (an antipyretic)‚ to reduce pain (an analgesic)‚ and to reduce swelling‚ soreness‚ and redness (an anti-inflammatory agent). Much of this is believed to be due to decreased production of prostaglandins and thromboxanes. Aspirin’s ability to suppress the production of prostaglandins and thromboxanes is due to its irreversible inactivation of the cyclooxygenase (COX)

Aspirin (ASA) is one of the most commonly used medication in our lives.it is found as analgesic and pain killer in 1899; today‚ it has developed other uses in addition to pain relief‚ such as reduction of inflammation and swelling‚ cancer prevention and treatment for heart attack and stroke. Especially‚ its effect on preventing and treating heart attack has been proven outstanding and efficient. Since aspirin is also an anti-coagulant‚ which means it lubricates the blood and effectively prevents

Ibuprofen and Acetaminophen Organic chemical compounds contain a vast number of isomers‚ molecules with the same molecular formula but different atomic arrangement‚ of which there are three types: structural‚ geometric and optical. The most closely-linked of isomers are optical isomers‚ which differ only by the three-dimensional placement of the molecule’s attachments‚ which renders its mirror images to be non-superimposable. The presence of optical isomerism within a molecule is determined by

synthesis of (S)-Ibuprofen‚ the compound is synthesized in nonracemic form directly from an achiral precursor. First‚ racemic ibuprofen was converted to aN achiral ketene via the acid chloride by adding thionyl chloride followed by triethylamine. Then‚ ketene was reacted with a chiral and nonracemic (S)-ethyl lactate produces a mixture of diasteromeric esters of ibuprofen derivatives where (S) configuration is predominantly. Finally‚ hydrolysis of the ester then provides (S)-ibuprofen in a relatively

Using the thin layer chromatography the major components of a commercial analgesic tablet will be indentified and purified. The active ingredients of the analgesic used were characterized by comparison with chromatograms of aspirin‚ acetaminophen‚ ibuprofen‚ mefanemic acid‚ and caffeine through the use of UV chromatography then the Rf value was calculated for each solvent. INTRODUCTION In this experiment‚ thin-layer chromatography (TLC) will be used to determine the composition of various analgesics

After the development of the TLC plate‚ it was placed under ultraviolet light for the spots resulted to be traced. The distance from the origin to the solvent front and the distances from the origin to the center of each spot formed were measured to calculate for the retention factor. The resulted retention factor of the unknown is 0.71 which is similar to ibuprofen which also has
