An ester is a compound that is formed when an acid reacts with an alcohol, -OH group. Aspirin is an acid because of the carboxylic acid group which gives the molecule a relatively stable anion (negatively charged form) which means that it can readily donate a proton. A Feasibility Study of an Extrusion-Based Fabrication Process for Personalized Drugs. However, salicylic acid is more acidic than aspirin, and is especially irritating to the mouth and stomach.

Determination of Aspirin using Back Titration This experiment is designed to illustrate techniques used in a typical indirect or back titration. His father was a weaver and dyer, and Bayer followed in his footsteps. Platelets are blood cells that stick together and block cuts and breaks in blood vessels, so they're important in normal health. This method of forming acetylsalicylic acid is an esterification reaction. It has been a while since we mixed it up with oil! The experiment conducted in this report will synthesize, purify and determine the percentage yield of aspirin. The titration of aspirin with NaOH. Just a few common ingredients and you are well on your way to ooohhhs and aaahhhs by everyone including adults with this alka seltzer science experiment.
