Acid-Base Extraction: Separation of an Organic Acid‚ Base and a Neural Compound Introduction/Background Acid base extraction is a widely used commercial method in separating acids‚ bases and neutral compounds. This is concept is based on several physical properties of the compounds‚ such as boiling point‚ melting points and solubility. The different solubility properties of the protonated and non-protonated forms of these compounds depend on the functional groups present‚ such

percent yields and the percent errors of each catalyst. In the end‚ we saw that for the sulphuric acid catalyzed aspirin‚ we saw an average of 69.7% percent yield and an average 30.3% percent error. As for the phosphoric acid catalyzed aspirin‚ we saw an average of 55.0% percent yield and an average 42.2% percent error. The Ka value for sulphuric acid is 1.0 x 10³ while the Ka value for phosphoric acid is 7.1 x 10⁻³. Knowing that the Ka value denotes the acidity of

EXPERIMENT 4: Synthesis of Salicylic Acid from Wintergreen Oil Abstract: The purpose of this experiment is to take methyl salicylate (wintergreen oil) and by heating it under reflux with NaOH as a solvent‚ and then cooling the mixture with H2SO4 as another solvent‚ synthesize salicylic acid. The final step involves purify the product to produce as pure a sample of salicylic acid as possible. This process allowed for the successful production of 1.406g salicylic acid‚ an 82.70% yield.
