The unknown tablet showed an Rf value of 0.584‚ closely matching that of caffeine (0.600)‚ suggesting similar polarity. The findings indicated that the unknown tablet likely contains caffeine or a closely related compound. Materials and Methods The materials required to complete

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

relative polarities of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen‚ and Caffeine based on their functional groups. The most overall polar analgesic is considered to be the analgesic that contained the most polar function groups. The amine and amide functional groups are the most polar. In this experiment‚ we found that both these functional groups are found in Caffeine. As a result‚ Caffeine was the most polar out of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen‚ and Caffeine. Aside from Caffeine

Addictive substances are becoming Substance abuse and addiction can changes ones life drastractly. To me substance abuse is when one over uses or depends on an addictive substance‚ and can not find a way to get away from it.

The purpose of this experiment was to answer a question: Which pill coating results in highest dissolution rates? This is important because dissolution of medicine such as ibuprofen prior to absorption maximizes effectiveness. Therefore‚ understanding how tablet coatings can affect dissolution time will be beneficial to consumers. Hypothesis: If the three types of pills are submerged in an acidic solution of pH 4.5‚ the gelatin coated capsules will dissolve quickest. This hypothesis came to be because

Ibuprofen (2-(4-isobutylphenyl) propionic acid‚ is a Nonsteroidal anti-inflammatory drugs (NSAID)‚ which is commonly used for the treatment of pain and inflammation. The concentration of ibuprofens found on drug stores is 100 mg of ibuprofen in 5 mL (20 mg/mL)‚ and the molecular weight is 206.28 (drugs.com). It is one of the most potent orally and highly active

Titration: Titrations are a quantitative chemical analysis technique. They are done to tell us how much acid is required to neutralise a certain quantity of alkali. A titration is a technique in which a solution of reactant (the titrant) is added to a solution of a second reactant (the analyte) until the end point is reached. The end point of the titration is the point at which the titrant has been added in the right quantity to neutralise the analyte. Usually you can see this by adding a reagent
