In Lab 19C “Determining of a Solubility Product Constant” I showed uses of the communication core competency. During the lab I was able to communicate well with my lab partner to complete the lab and to work on the calculations and recording of our data. We both divided up the work equally, with both of us doing tasks in shifts or working on separate tasks so that we could complete the lab efficiently and accurately. Our roles included one person creating the chemical reaction in the beaker, and one person writing down observations which we would alternate doing. We also often had one person cleaning our equipment while the other set up for another trial. We shared our ideas with one another throughout the lab like our observations on the colour and precipitate produced in the test tubes, and on ways to complete the post lab calculations. In the second part of the lab, we had to heat up the beakers seen above to see what temperature the precipitate would dissolve at. We worked together to accurately observe when the precipitate was completely dissolved, often times it was hard so see when this happened so we discussed what we personally saw and if the solution needed to be heated for longer. We had some obstacles in this part with it taking a long time for certain precipitates to dissolve so we split up our roles again with one person observing the reaction and another cleaning and putting away equipment we weren’t using anymore. When the lab was finished we discussed our answers to the post lab questions to see if we had similar results and that we did our calculations correctly. Over all, I believe that me and my partner showed great communication and collaborating skills through assigning roles and responsibilities, sharing ideas and using strategies to navigate project goals.
