Chemistry 12 Lab 19C

Core Competency Collaboration

For this lab19C, the goal was to figure out the approximate Ksp value for PbI2 by mixing various concentrations of solution. My partner and I collaborated well to set up quickly and effectively. We each took a different solution (one had Pb(NO3)2 and the other had KI). We split the water so we could fill up our test tubes faster but with accuracy. Our immediate results showed a precipitate formed in 4/6 test tubes with the precipitate gradually getting lighter. We then had one person watching our test tubes heat up while the other started cleaning our leftover supplies. We communicated well to ensure we were both at the same step and kept our station organized by labelling anything we could as to not mix up any solutions. Our collaboration skills were vital to the success of this lab as if we didn’t collaborate there was no way to finish on time.
