Our data displayed supports the notion that by increasing the acidity of the catalyst‚ the production of aspirin will increase. Our hypothesis was proven correct. In our data‚ we calculated the percent yield and percent error of each trial. We also calculated the average of the percent yields and the percent errors of each catalyst. In the end‚ we saw that for the sulphuric acid catalyzed aspirin‚ we saw an average of 69.7% percent yield and an average 30.3% percent error. As for the phosphoric acid

For this lab‚ 40.2 mL of canola oil were used as the initial volume for the production of synthesized biodiesel. Through the synthesis process‚ 31.307 grams of canola biodiesel was produced‚ which is a percentage yield of 85.714%. In order to get this percentage yield‚ the following calculations were made: 40.2 mL canola oil × 0.9073 g1 mL=36.5 g × 1 mol376.6 g=0.0416 moles canola oil From the prelab‚ for every 1 mole of oil‚ 3 moles of biodiesel are produced. 0.0416 mol oil × 3 mol biodiesel1

Tie-Dye Grignard Synthesis Abstract: 4-Bromo-N‚N-dimethylaniline underwent a Grignard reaction with diethyl carbonate to produce a type of the tie-dye chemical triarylmethane. This specific triarylmethane produces a vivid crystal violet color when dyed. The experiment was first heated under reflux to produce the necessary Grignard reagent as a grey liquid. It was then reacted with diethyl carbonate and hydrochloric acid to produce crystal violet. The resulting chemical was very absorbent to
