Chemistry Lab
In the past few weeks in Chemistry, we have been doing a two-part lab. The first part was creating a chemical that we didn't know what it was. Later we found that it was a toxic chemical called wintergreen. This name probably sounds familiar, it's used in toothpaste, candy and muscle healing ointment. Surprisingly, the chemical is highly toxic and can kill you if you digest to much. The only max allowed amount used in products that will be digested in 0.04%. The next part of the lab was to test how wintergreen works as an antibacterial. Our teacher put some bacteria on the dish and we spread it around. We put a sample of wintergreen, aspirin with water, distilled water and methanol on a petri dish. After a few days, the bacterial grew and we looked at how much space around the samples there were. The more space between the samples and bacteria, the stronger the antibacterial. Here is my lab write up. It shows the steps and my observations.
Here is the bacteria samples with the antibacterial samples:
