How many grams of aspirin are needed to generate an osmotic pressure of 6. It is a modifier of the enzymatic activity of cyclooxygenase-2 (COX-2). add a few drops of sulfuric acid and swirl the flask for a few minutes 4. point/freezing point Melting point/ range: 165. 4. 8. ) Aspirin Titration with base 6. It was withdrawn from medicinal use as dangerous Ideally, the material to be recrystallised should be sparingly soluble at room temperature and yet quite soluble at its boiling point. Advanced search Similarity search. To get a correct measure of boiling point the thermometer should be above the level of the surface of the boiling liquid and be Empty (g) With aspirin (g) Aspirin weight (g) 25 27 1. 7 °C, and Kb for chloroform is 3.
