Contents 1.0 Abstract Acetaminophen and aspirin are both well-known drugs that relieve pain and reduce fever. This report looks at acetaminophen as a potential substitute for a patient who is allergic to aspirin. Acetaminophen‚ a common analgesic drug that can be bought over the counter‚ was synthesised by Hormon Northrop Morse. With acetaminophen consisting of a benzene ring‚ an amide and an alcohol group‚ it has the ability to stop pain and reduce fevers. However‚ due to the state of technology

Preparation of Sodium Chloride through titration Abstract: acid-base titration is a technique commonly used to determine the moles of acid in a sample by adding a known volume of strong base of a known concentration. The strong base provides the hydroxide ion‚ to react quantitatively with the acid. The point at which the acid is completely and exactly consumed the known quantity of base is called the equivalence end point and is signalled by a colour change in the solution (end point). This colour

valuable analytical technique. It provides a rapid separation of compounds‚ and gives an indication of the number and nature of the components of a mixture. TLC can also be used to identify compounds by comparison with known samples‚ to check the purity of a compound‚ or to monitor the progress of a reaction‚ an extraction‚ or a purification procedure. This experiment will introduce you to the mechanics of TLC‚ and the chemical principles behind it. TLC is normally done on a small glass or plastic

three different samples of 100 uL of isolated A. fischeri chDNA solution each were obtained. Next‚ to determine the purity and concentration of the isolated A. fischeri chDNA samples‚ UV spectrophotometry was performed using two different spectrophotometers. The best sample was chosen for the next step in the experiment‚ restriction digestion‚ which had a concentration of 196.6 ug/uL. Purity analysis shows a 1.83 for the ratio of A260/A280 and a 2.15 for the ratio of A260/A230. Both of these values are

Dogs are very stoic creatures. They suffer in pain silently - always trying to please their masters and keep them happy. Dogs will continue their daily routine as long as possible - sometimes to their own detriment. So it’s up to you to keep a watchful eye on your dogs‚ assessing their quality of life and keeping them safe‚ sound and happy. How Do I Know My Dog Needs Glucosamine Chondroitin for Dogs Dogs exhibit many of the same symptoms as people when they’re in pain. What you need to be on

identifying a particular drug as the size‚ color‚ and shape of the crystals will differ for each specific drug. 5. What is spectrophotometry? How can this useful in identifying drugs? A spectrophotometry device can emit both UV and infrared light as it measures how a sample either reflects or absorbs. Though ultraviolet spectrophotometry cannot identify a drug‚ infrared spectrophotometry can‚ since the pattern of light is unique to each type of compound. 6.

Experiment # 3 Acetylsalicylic Acid Introduction: The purpose of this experiment is to create and isolate pure acetylsalicylic acid from the substances salicylic acid and acetic anhydride. Then one will find the melting point to determine purity. Procedure: Make a hot bath. Weigh some salicylic acid and place in conical vial. Add .480mL of acetic anhydride and a drop of concentrated phosphoric acid. Drop in a magnetic spin vane and attach air condenser to vial. Partially submerge it in

12th Nov LS4002 - EXPERIMENT 1 Quantitative Analysis by Acid-Base Titration - A Determination of the Quantity of Aspirin in Powdered Tablets Aims In this experiment a solution of sodium hydroxide will be standardised using potassium hydrogen pthalate. This standardised sodium hydroxide solution will then be used to titrate powdered aspirin tablets. The percentage of aspirin in the powder tablets will then be calculated. Introduction Acid-base titrations are an example of what is called volumetric

examining the color and morphology of the crystals. This test is more specific than a color test when trying to identify a certain drug based on the size‚ color‚ and shape of the different crystals. 5. What is spectrophotometry? How can this be useful in identifying drugs? Spectrophotometry is a ultraviolet test. It is useful to help determine if there is a drug present. Critical Thinking Questions 1.
