Creating a Precipitate Lab Julia Wu Purpose: The purpose of this lab was to use Calcium Chloride and Magnesium Sulfate to produce 2.00 grams of precipitate. Materials: calcium chloride, magnesium sulfate, two beakers, two flasks, funnel, and filter paper. Procedure: Write the balanced equation for Calcium Chloride and Magnesium Sulfate. Calculate how much of each reactant is needed to produce 2.00 grams of precipitate. Once you have calculated the amount of each reactant, proceed to the lab table and retrieve the following equipment: two graduated cylinders, two beakers, two flasks, funnel, and filter paper. Take the mass of the filter paper. Pour the right amount of each reactant, into the two beakers. From…show more content…
The percent yield was calculated to be 64.5%. Overall, this experiment was pretty efficient. One error that could have affected the actual yield is that when pouring the solution into the filter paper, some of the solution could have spilled out or when finished pouring the solution, some of the precipitate was still stuck at the bottom of the flask. Secondly the filter paper might not have been folded correctly. If that were to happen, some of the precipitate would have escaped through the paper and into the second
