...) (AS) Which type of acid (monoprotic or diprotic or triprotic) is the most effective in the purification process? A monoprotic acid is one that can donate one proton per molecule during the dissociation process; a diprotic can donate two and a triprotic can donate three. Hydrogen chloride (HCl) is an example of a monoprotic acid, sulphuric acid (H2SO4) an example of a diprotic and Phosporic Acid (H3PO4) an example of a triprotic acid. In the back titration process, an acid needs to be used. By using each of these three acids in the experiment, we can see which is the most effective (fastest and most accurate). 5) (A2) How is aspirin synthesized? To answer this, it is necessary to complete the synthesis...

...acid. Aspirin blocks an enzyme called cyclooxygenase, COX-1 and COX-2, which is involved with the ring closure and addition of oxygen to arachidonic acid converting to prostaglandins (Prostaglandins, 2003). It should be noted that Prostaglandins are responsible for causing pain, fever, blood clotting, gastrointestinal tract, uterine contractions etc. The acetyl group in aspirin has the ability to block an enzyme called COX1 and COX 2 which is reacting with arachidonic acid or prostaglandins.
