I displayed the Communication Core Competency within the lab through me and my lab partners’ teamwork. I understood and shared information throughout the lab, so we all learned actively together. Once my lab partners explained to me why a precipitate forms at a cooler temperature, I understood the difference between adding heat to an equilibrium system and “removing heat”/ lowering the temperature of the equilibrium system. I also shared the information of when a precipitate dissolved at a specific temperature and took responsibility through telling my partners when I was going to begin another task: measuring the specific solution, cleaning up unused supplies, etc. I also collaborated with my partners by recognizing different points of view so we can come to a clear consensus. There was a minor debate of when a precipitate had dissolved completely, but the steam of the hot water fogged up the test tubes, making it difficult to know whether or not it was dissolved, or a slight precipitate remained. We all respectively shared our points of view and even invited a third party to assess our tubes for an objective opinion. Lastly, I worked with my lab partners to achieve a goal by working on different parts of the lab to be efficient. Part of our picture was us taking turns in stirring the precipitate in the beaker. We achieved our goal of determining what the approximate Ksp value of the Lead (II) Iodide at 19 degrees Celsius, which turned out to be the following expression:
4.0*10^-9< Ksp < 1.4*10^-8
