sample. Depend on the result‚ the more polar compound like caffeine has small Rf value (average 0.12) because it didn’t travel with the solvent. The Acetaminophen are less polar than the caffeine but more polar than the Aspirin and Ibuprofen and has average Rf value (0.4). The Aspirin has more Rf value (average 0.55) than the Caffeine and the Acetaminophen because it is less polar and travel with the solvent. The ibuprofen has the bigger Rf value in this experiment (average 0.7) because it has the lower

Answer 2a: [pic] Question 3 Three aspirin tablets‚ which were claimed by the manufacturer to each contain 320 mg of aspirin‚ C6H4(OCOCH3)COOH‚ were heated gently in 50.00 mL of NaOH solution of concentration 0.5190 mol/ L. The aspirin tablets reacted according to the equation: C6H4(OCOCH3)COOH(s) + 2NaOH(aq) ( C6H4(OH)COONa(aq) + CH3COONa(aq) + H2O(l) After cooling‚ the solution

comes off the field‚ an athlete notices he has a subtle pain in his shoulder. Determined to finish out the season strong‚ he takes two tablets of aspirin in hopes of healing the beginnings of an injury. What the athlete does not know about the painkillers could affect him later down the road‚ especially if he upholds his mentality of constantly taking aspirin whenever he senses an injury in the making. Painkillers are drugs that simply mask the pain many people suffer from on a daily basis. Globally

It’s important to understand what they are‚ what they do‚ how they are broken down in the body (physically and chemically) and what diseases they can either treat or cause. Certain drugs do certain things. Alcohol can lower inhibitions while Morphine can completely take away pain for hours at a time. I briefly explain these above drugs and give details about each.

Commercial Analgesics 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

The calculations completed for this experiment include determining the amount of Na2CO3 needed to do a full reaction. This was calculated through stoichiometry calculations: Molar mass was first calculated for CaCl2*2H2O Ca = 40.078g Cl2 = 35.453g*2 = 70.906g 2H2 = 1.00794g*4 = 4.03176g 2O = 15.9994g*2 = 31.9988g 40.078g + 70.906g + 4.03176g + 31.9988g = 147.01456g or 147.0 g CaCl2 1g CaCl2 * 2H2O x (1 mol CaCl2 *2H2O/147g CaCl2 *2H2O) = 0.0068 mol of CaCl2*2H2O Molar mass was then

long-term treatments‚ or for anesthesia during some smaller procedures. (3) Aspirin is used for minor aches and pains. Aspirin is in a group of medications called nonsteroidal anti-inflammatory drugs (NSAID). Once aspirin is dissolved into the bloodstream it attaches to an enzyme called COX-2. COX-2 produces chemicals called prostaglandins that allow your body to feel pain. Aspirin prevents prostaglandins from working. Aspirin is also used to prevent heart attaches and prevent blood clots from forming

Objective: In steam distillation lab (lab 3)‚ we must obtain pure Eugenol from cloves through the process of steam distillation. In the crystallization lab (lab 4) part 1‚ we must acquire the best possible pure crystallization of acetylsalicylic acid from aspirin and in part 2 we must obtain a similar pure crystallization of benzil from an impure mixture of benzil.

Keri Sage A&P 2530 Effects of Selected Drugs Anesthesia uses a great amount of drugs to suppress pain that would occur in the body. Alcohol‚ Aspirin‚ Lidocaine‚ Morphine‚ Ketamine‚ and Succinylcholine are drugs used during anesthesia. These drugs are used to interrupt pain signals during surgical procedures. ~ For decades people have been using the effects of alcohol to suppress their pain. In the early 1900’s a physician suggested to use intoxicating amounts of alcohol before medical procedures
