Aspirin Lab Day 2
This is the second day of the aspirin lab. On this day, we did the last 2 steps of the lab. After we let the mixture sit overnight, the crystals formed the right way. If it didn't we would have had to scratch the side of the beaker with a stirring rod to induce crystallization. But, we didn't have to do that. To collect the product, we used a buchner funnel and filter paper to separate the water and the product. We also used a vacuum made by a tube and running water to suck out all the water on the aspirin. This process is called suction filtration. After we ran it for about 15 mins, we placed the filter paper and aspirin on the lab bench. We are gonna let them completely dry over the fall break and then we are going to measure it and see what percent yield we had. This is the end of day 2.

Your description of the lab is very good. You made sure to include all the parts of the lab, as well as describing their purpose. Great job Varun!
ReplyDeleteThanks Kyle
ReplyDeleteI agree with Kyle's comment. Your post was easy to follow along with and gave enough detail of the lab to give the reader a good idea of what we did, but not too much that I was overbearing. Good Job! I hope you were able to make a lot of aspirin.
