Day 99: Percent Yield Lab

For Day 99, students made calcium carbonate by reacting solutions of sodium carbonate and calcium chloride. They learned how to use gravity filtration and had a friendly competition to see who could get the best percent yield (which we learned how to calculate today). This lab was a nice introduction to the need for theoretical yield and percent yield calculations as well as the need for converting mass to moles before using a BCA table.
