The Lab 19C was about determining an approximate Ksp value for PBI2 at room temperature. During the lab, I collaborated with my partners and shared our observations. Test tubes A, B, C, and D have ppt form (yellow), whereas E and F have not changed at all. We also observed what temperature caused the precipitate in each test tube to dissolve, as shown in the photo. One person swirls the test tubes until they dissolve, while another records the temperature. I also cleaned the materials because we didn’t have enough time. I demonstrate my appreciation for feedback from others in my group by actively listening and asking questions. After the lab, we had to finish the observations&data paper. I didn’t know how to calculate Trial Ion Product, so I asked one of my partners and she told me how to. However, I was still not sure, so I asked again and found out there was a mistake. We fixed together and helped each other.
