aspirin testing

Title: Aspirin TestsPurpose: The purpose of this experiment was todetremine if the sample of aspirin contained phenol, starch, acid, and an esterExperimental: The experimental process involved determining the presence of these substances in the sample of aspirin provided. The experiment began with the weighing of the sample of aspirin provided. It was followed by testing the presence of phenol, which was followed by the test of the presence of starch. This was followed by the test of acid in the aspirin sample. The final test was the presence of an ester in the acid.eactions was recorded and observations noted. The results were recorded in tabular form. The results were explained and conclusion drawn.Experimental set-up and/or reaction(s) Experiment 1. Procedure: -Recrystallized aspirin was weighed to determine the percentage yield. The weight was found to be 1.224g Experiment 2. A few crystals of salicylic acid were added to the first three test tubes and the color was observed to be dark purple. A few crystals of salicylic acid were added to the second test tube and the color was observed to be light purple Commercial aspirin was added to the third test tube and the color was obseved to change from purple to brown 3ml of water was added to each tube and mixed with a vortex mixer. 4 drops of 0/1% ferric chloride was added to each tube and the results noted on a report sheet. Experiment 3. A small amount of commercial aspirin was added to one tube and the color was observed to be green. Recrystallised aspirin was added to another test tube and the color was observed to be brown 4 drops of Lugol’s reagent were added to each tibe and the color noted Experiment 4. -A small amount of salicylic acid was added to one test tube and a small amount of recrystallised aspirin to another tube. 3ml of water was added to each tube and mixed with vortex mixer. - 2 drops...
