Asrin Synthesis Lab Report

225 Words1 Page

In the beginning of our experiment of the synthesis of aspirin, we believed that if the catalyst increases in Ka value, i.e. acidity, and the conjugate base(s) do not react, then the percent yield of aspirin will increase when percent yield is a function of the acidity of the catalyst. While performing the experiment, we discovered that the sulfuric acid dissociated the most, which allowed the substance to have the greatest percent yield. This is due to the fact that the increased dissociation allows for more hydrogen protons to be donated. The sulfuric acid had the highest percent yield with a value of 69.7%. In addition, the phosphoric acid dissociated less than the sulfuric acid due to its lower Ka value.
