  Lab: The Gravimetric Analysis of Lead in Contaminated Water Mark as Favorite (48 Favorites)

  In this lab, students will perform a gravimetric analysis of a simulated water sample contaminated with “lead”. Using their knowledge of solubility and chemical reactions they will precipitate the “lead” from the water sample. Then from the data collected, they will calculate the concentration of “lead” in their samples and compare that value to those found in water samples from the Flint, Michigan water crisis.
