current experiment I will asses the pharmaceutical preparation of Panacetin‚ by using it ’s solubility along with other organic molecules. We know that Panacetin is made up of sucrose‚ aspirin and some other unknown substance. We know the substance has to be Phenacetin or Acetanilide. To help solidify our reasoning‚ we need a % recovery of 8-12% sucrose‚ 35-45% aspirin and 45-55% unknown. Sucrose for example is insoluble in dichloromethane‚ while aspirin is soluble in CH2Cl2‚ but not in H2O. The organic

Title of Experiment 12: The Effect of Ionic Strength on the solubility of an Electrolyte Aim: The purpose of this experiment was to determine the thermodynamics variable of enthalpy‚ ∆H for the dissolution reaction of boric acid in water. The solubility of boric acid was measured over a range of various temperatures by finding out at what temperature crystallization began for solution of different molarities. A graphical relationship between the natural logarithm of molal concentration and the inverse

Too much sugar = Crystallisation Too little sugar = fermentation (Store jams completely covered in a cool place) Fruit Sugar Pectin Acid Use ripe fruit Fruit high in pectin Acidic fruit Examples include blackcurrants and cooking apples. Needs to be accurately weighed. Too much causes crystallisation. Warmed sugar will dissolve quickly. Granulated sugar is generally used. Sure-set sugar is ideal for

The purpose of this experiment is to investigate the composition of a simulated pharmaceutical preparation Panacetin‚ a proposed type of pain-killer. Panacetin is typically made up of sucrose‚ aspirin‚ and acetaminophen‚ but the third component in this experiment is unknown. The unknown component is suspected to be a chemical relative of acetaminophen‚ either acetanilide or phenacetin. Using techniques such as extraction‚ evaporation‚ and filtration‚ the three components will be isolated based on

Five COX inhibitors were used to validate the assay‚ indomethacin‚ aspirin‚ naproxen‚ ibuprofen‚ and the arylsulfonamide NS-398‚ all with different COX selectivity and time dependency. Time-dependent inhibition was determined by comparing the inhibition‚ with and without preincubation of enzyme and inhibitor. Two flavonoids

Medical Marijuana is also a good medicine to help get rid of headaches and migraines. “Some people find it so useful in gaining perspectives or seeing problems from a different vantage point that they smoke it in preparation for intellectual work.” (Grinspoon) This is actually something thats very debatable‚ its also a very hot topic right now. Many people in the US smoke marijuana because it gives them a difference mindset and helps them get new ideas to problems or

Like all drugs‚ aspirin also has some undesirable side effects which should be noted. When taken in large quantities (several grams per day)‚ gastric problems can result. Its use has been implicated in Reyes syndrome‚ a brain disorder that can affect people under the age of 18. Some people are highly allergic to aspirin. Finally‚ aspirin interferes with platelets and affects normal blood clotting which can lead to hemorrhaging
